after t seconds, the heat rate is: Qdot = mw . (cp2 . T2 - cp1 . T1) / t control volume thermodynamics Ein - Eout = dE/dt (assuming steady) Ein = Eout Qdot = mout . u2 -------eq1 at T2=120C P2=gauge pressure reading just before opening the valve then from steam tables, we get u2 and...

Ignore the previous question. now let's say that the tank is vacuumed and has a volume "Vt", and the valve is closed then a volume "Vw" of water at T1=20C is added to the tank water is heated using an external heat source (coal combustion) until its temperature reaches T2=120C what is the mass...

this is a part of a senior project that I am working on. you can assume anything to simplify it assume it's a bachelor's degree level question

a cylindrical tank with volume V a volume of water is inside the tank and the rest is air now if coal combustion is releasing heat into the tank Qin and when the gauge reads a certain pressure "P", the valve is opened which allows steam to exit the boiler what's the mass flow rate of the steam?
