Flow velocity Cross-sectional area (pressure 10 1) (t 20) (t t).

Commonly used measuring instruments in meteorology include liquids (e.g., mercury.

There are two types of barometers: barometers and solid (such as metal empty boxes). Barometric pressure recordings are measured by a barometer or barometer installed in a well-lit baropressure chamber with little variation in temperature.

There is a timed barometric pressure record and a continuous barometric pressure record. The timed pressure record of manual visual measurement is measured by a moving trough or fixed trough mercury barometer, and the basic station observes 4 times a day and the base station observes 24 times a day.

In a high-pressure environment, all tissues of the body are gradually saturated with nitrogen (generally after 5-6 hours of working under high pressure, the human body is saturated with nitrogen), and when the human body returns to the standard atmospheric pressure.

, excess nitrogen is expelled with exhalation, but this process is slow.

If there is a sudden return to standard air pressure from a high-pressure environment.

environment, a part of the nitrogen accumulated in the fat may stay in the body, and swell to form small bubbles, blocking blood and tissues, easy to form air embolism and cause diseases, and in severe cases, it will endanger human life.

The impact of air pressure changes on human health is more manifested in the generation, disappearance or movement of the circulating weather situation represented by high pressure or low pressure. Under the situation of low pressure circulation, most of the weather is cloudy and rainy, and the change of wind is obvious. In the situation of high-pressure circulation, it is mostly sunny and the weather is relatively stable.

The easiest way is to install a flowmeter that is more accurate, and the error of your own direct calculation is very large. Flow rate = equivalent volume x pressure of falling atmosphere. The equivalent volume is enough for you to calculate, pipes, leaks, etc.

There are three main technical parameters of the air compressor, motor power, exhaust volume and the air pressure you give, if you want to match the air compressor, the easiest way is to calculate the sum of each gas equipment, and the three indicators can meet two before you can match the air compressor you need, and it will also involve the size and length of the gas pipeline.

The calculation of the gas flow rate in the pipeline refers to the standard state flow rate of the gas or the gas flow rate under specified operating conditions.

The formula for the gas flow rate without temperature and pressure condition correction is: Flow velocity The formula for the gas flow rate with temperature and pressure condition correction for the cross-sectional area is:

Flow velocity Cross-sectional area (pressure 10 1) (t 20) (t t) Pressure: the pressure of the gas at the current-carrying cross-section, mpa; t: absolute temperature, 273 15

t: the actual temperature of the gas at the current-carrying section 2, q dn dn v (p1 1bar) 353q is the standard flow rate; dn is the pipe diameter, such as DN65, DN80 and other direct input numbers, there is no need to convert to the inner diameter; v is the flow rate; P1 is the working pressure, and the unit is kilogram bar;

If the standard condition Q flow rate is available, the working condition Q is easy to calculate, Q pb pm q, pb is the standard atmospheric pressure, pm pb p1; pm＝pb＋p1。

I used to work as a stoker, I burned tons of coal furnace, the diameter of the steam supply pipe is six centimeters, the steam flow rate is incalculable, because it involves how many kilograms of steam pressure at that time, the larger the number of kilograms, the greater the flow of steam flowing through six points per minute, and vice versa.

Summary. Hello <>

The calculation method of the total scale of gas consumption of enterprises is determined according to the type of gas used by the enterprise, the amount of gas used, and the time of use. To put it simply, it is obtained by adding up the actual gas consumption of the company in each time period. For example, if a company uses natural gas and uses 100,000 cubic meters of natural gas in a year, the total size of the company's gas consumption is 100,000 cubic meters.

In addition, the calculation of the total scale of gas consumption of enterprises is also affected by factors such as different regions, different industries, and different gas pressures. Therefore, in the specific calculation, it needs to be adjusted according to the actual situation.

Hello <>

The calculation method of the total scale of gas consumption of an enterprise is determined based on the type of gas used by the enterprise, the amount of gas used, and the time of use. To put it simply, it is obtained by adding the actual gas consumption of the enterprise in each time period with the absolute concession. For example, if a company uses natural gas and uses 100,000 cubic meters of natural gas in a year, then the company's gas consumption is 100,000 cubic meters.

In addition, the calculation of the total scale of gas consumption of enterprises is also affected by factors such as different regions, different industries, and different gas pressures. Therefore, in the specific calculation, it needs to be adjusted according to the actual situation.

The total scale of gas consumption of enterprises refers to the total amount of gas used by enterprises in a certain period of time. In the actual operation of enterprises, the total scale of enterprise gas consumption usually becomes one of the important indicators of enterprise gas consumption. There are also some related concepts related to the total scale of gas consumption of enterprises, such as gas consumption in specific links, energy consumption per unit of product, etc.

These indicators can help enterprises better evaluate their own gas consumption, optimize their gas consumption plans, and improve energy efficiency. In addition, it is worth noting that the calculation of the total scale of gas consumption of enterprises should also take into account the influence of factors such as gas loss and measurement error. Therefore, in the actual calculation process, corresponding corrections and calibration need to be carried out to ensure the accuracy and reliability of the calculation results.

How to calculate gas consumption:

First, determine the pre-metering needle reading.

Determine the gauge hand reading after measurement.

The meter reading after measurement minus the meter reading before measurement is the gas consumption.

The red hands or red display number of the dial or display window are less than 1m3 and are not included in the calculation.

Gas unit price: The amount of gas used.

1000 liters, about equal to kilograms. One cubic meter of natural gas is equal to about a kilogram. Known conditions:

1. Calculation formula: mass of gas = molar mass of gas (grams) x volume of gas (liters) liters). 2. One cubic meter (m) of natural gas = 1000 liters (l) of natural gas.

3. The main component in natural gas is methane (CH4), and the molar mass is 16 grams of mol. Then according to the calculation formula: the mass of 1 cubic meter of natural gas = 16 (gram mol) x 1000 (liter liter mol) = gram kg.
