Find the steam weight, five kilograms of steam density

From the equation of state of an ideal gas pv=nrt, we get v=nrt p, where n is the amount of matter, and when n=1, it is the molar volume of the gas; r=,t= k, so v= l mol, and the molar mass of water vapor is 18 g mol, so the density is.

According to the inscription, the volume of water vapor flowing out in one hour is 4*, so the mass is the product of density and volume equal to tons.

This is calculated using the equation of state of an ideal gas, but because of the polarity of the water molecule, its error will be very large, and it is better to use the pro2 software to simulate it

Pipe diameter = 400mm = hours = 3600s

volumetric flow per hour;

square* meters cubic.

Look up the table and the vapor density under this parameter is kg m3

Kilogram hours = tons hours.

There is something wrong with the first one; The calculation method of the sub-worm is correct.

Five kilograms of steam density kilograms cubic meters. The density of the oak at a wide pressure is kilogram cubic meters, so the volume of 1 ton of water vapor is equal to 1000 cubic meters. Steam is classified according to pressure and temperature as:

Saturated steam, superheated steam. The main uses of steam are: heating and humidification; It can also generate power; Ryo Sakuno is driven by machines, etc.

Saturated steamWhen a liquid evaporates in a limited confined space, the liquid molecules pass through the liquid surface and enter the upper space and become vapor molecules. Due to the chaotic thermal motion of the vapor molecules, they collide with each other, and collide with the container wall and the liquid surface, and when they collide with the liquid surface, some molecules are attracted by the liquid molecules and return to the liquid to become liquid molecules. When evaporation begins, more molecules enter space than there are molecules in the liquid returning.

The difference in values is tons. One kilogram of steam should be equal to a ton, and one kilogram of dissipated Kaiqi catty is one kilogram, so 6 kilograms of water vapor.

It is a ton, 10 kilograms is a ton, and the subtraction of the two is the difference between the value, that is, the ton.

According to the relationship between weight and cube, 1 ton is equal to 1 cubic, then 1 ton is equal to 1000 kg, and Sun's means that one thousandth of steam is equal to a ton, that is, a cubic meter.

Tons of patting cores. 1000 g = 1 ton, 2400 kg = 2400 1000 tons = ton. So 2400kg = tons.

Kilograms, grams, and tons are the international units of measurement.

The conversion method of collapse is that one ton is equal to one thousand kilograms, one thousand micrograms is equal to one milligram, and one ton is equal to one million grams. Raid shirt digging weight unit.

With a long history, China has specific units of measurement in catties and kilograms.

The density of water vapor is kilogram cubic meters So the volume of 1 ton of water vapor is equal to 1000 cubic meters When the liquid evaporates in a limited confined space, the liquid molecules enter the upper space through the liquid surface and become vapor molecules. Due to the chaotic thermal motion of the vapor molecules, they collide with each other, and collide with the container wall and the liquid surface, and when they collide with the liquid surface, some molecules are attracted by the liquid molecules and return to the liquid to become liquid molecules. At the beginning of evaporation, the number of molecules entering space is more than the number of molecules in the returned liquid, and as evaporation continues, the density of space vapor molecules increases, and so does the number of molecules in the returning liquid.

When the number of grinding molecules entering the space in the unit time ruler is equal to the number of molecules in the returned liquid, the evaporation and condensation are in a state of dynamic equilibrium, and although the evaporation and condensation are still in progress, the density of the vapor molecules in the space no longer increases, and the state of pure combustion at this time is called the saturation state. The liquid in the saturated state is called a saturated liquid, and its vapor is called dry saturated steam (also known as saturated steam).
