Anonymous users2024-02-15PN40 is vaguely said, but it can't be said that PN40=, the latter one must have units, PN40 is in accordance with the HG20592-2009 standard, but according to the JB standard. Their meaning is the same.
The high-pressure turbine flowmeter can display many flow units, including cubic meters, gallons, liters, standard cubic meters, standard liters, etc., and can set fixed pressure and temperature parameters to compensate for the gas.

Anonymous users2024-02-14It means that the nominal pressure is 4MPa, which is equivalent to 40 kg pressure, and it is common sense not to write the MPA of the unit with PN. Everyone knows that the unit is megapascals, and 1megapascal is equal to kilograms.

Anonymous users2024-02-13Pressure: 4MPa
4MPa means millimeter per square meter.
4 Newtons, i.e., 4n mm 2 = 4xg cm 2 where g is the acceleration due to gravity.
g = kilogram meters seconds 2 is usually replaced by 10 kilogram meters seconds 2.
Therefore: 4MPa = 40kg cm2
The exact amount of pressure you need to measure or calculate the force area, and then calculate to know.

4MPa means 4 Newtons per square millimeter, i.e. 4n mm 2 = 4xg cm 2 where g is the acceleration due to gravity, g = kilogram meters second 2 is usually replaced by 10 kg meter second 2.
Therefore: 4MPa = 40kg slag Dabo cm 2
Specifically, you need to measure or calculate the force surface such as auspicious product, and then calculate to know.

Anonymous users2024-02-05How much pressure is PN10, what I read on the Internet Some say it's 10MPa (100 kg), some say it's 1....
Answer: 1 kilogram is commonly used in engineering to refer to a standard atmosphere, 1mpa = 10 standard atmospheres, so 1mpa = 10 kilograms.

On the pressure gauge is 50,000 kg of pressure. MPA is a unit of pressure, which means that there is a pressure of 500,000 Newtons per square meter of area, that is, a pressure of 50 Newtons per square centimeter of area. 500,000 Newtons are generated, and such a force is equivalent to 500,000 Newtons pressed on top of 500,000 Newtons is about 50,000 kilograms of weight, and 50 Newtons is about 5 kilograms of weight. >>>More
This refrigerant is a hybrid refrigerant. Once there is a leak in the system, the refrigerant in the system should also be discharged, re-vacuumed, and refilled. As for the high and low pressure range, for air cooling, the high pressure is 28-35 bar, and the low pressure is about 6-8 bar. >>>More
x Measure the high and low pressure of the air conditioning system, the engine should be running at idle speed, and the ambient temperature should be measured at 35. Normal high pressure pressure should be or 190-250lbf in2); Normal low pressure should be between or 20-35lbf in2). If the low pressure is higher or lower than this range, it means that the expansion valve is not properly adjusted. >>>More
