The issues of temperature and pressure
Thread Content
It is a tank with an inner diameter of 900; the height of the upper and lower end caps together with the cylinder body is 1365 (the size of the inner cylinder). A 57-mm semi-circular coiled tube is installed around the cylinder body to heat the contents of the tank, with steam flowing through this coil. The tank is filled to 4/5 capacity with alkaline solution, and it remains sealed during heating. What is the steam temperature inside the coil when the steam pressure is 0.4 MPa? What is the pressure inside the tank when its temperature reaches 125°C?
1. Find the saturated vapor pressure of the medium at 125 degrees, and then determine the operating temperature! !
These questions should be answered unconditionally by the guy who gave you the equipment design requirements sheet!
I think the pressure in the storage tank should have nothing to do with the heating steam! The steam coil is used solely to maintain the temperature of the storage tank and prevent the alkali solution from solidifying; such alkali tanks are generally at atmospheric pressure.
Everyone, please help me figure out what would happen if the tank is 4/5 full of water
