Hi there,
I have a question regarding compressor head. Is it accurate to state that Head is defined as the amount of energy it takes to compress a mass of gas from a certain suction pressure to a certain discharge pressure?
I know that, for a fixed discharge pressure and compressor speed, if...
Hi there,
Does anyone know how to calculate the wetted surface area of a partially filled horizontal vessel with elliptical heads i.e. not hemispherical ends?
Your help would be appreciated.
I agree that the thermal relief rate will not drastically affect valve sizing.
However, the required relief rate is directly proportional to the cubical expansion coefficient.
Q = (B*H)/(500*G*C) API 521
where Q= Thermal relief rate, B = cubical expansion coefficient, H= heat transfer rate...
I am currently sizing a PSV which is situated on the discharge of a heat exchanger. The relieving fluid is cooling medium i.e. 75%potable water/25% MEG. Based on API standards, I have sized a rupture disc to prevent against tube rupture and process gas breakthrough. Therefore,the only credible...
