patylomy7 2022-08-13A work done on the steady flow system is 30 kJ/kgm. Calculate the heat in HP if the mass flow rate of fluid is 10 kg per minute given that the internal energy is decreased by 10 kJ/kgm and the fluid flow is increased by 20 kJ/kgm. Also, identify if the heat is added to the system or rejected by the system.

Bierlehre59 2022-08-13When we are dealing with a gaseous thermodynamic system, in books it's written that state of the system can be described by only two independent variables from the three (p,V,T) . But it's not written why or how? Why we have to choose only two independent variables, why not more or less? I've gone through some answers but still unable to understand.
