Question

A nitrogen line, 540 R, and 75 lbf/in.², is connected to a turbine that exhausts to a closed initially empty tank of 2000 ft^3,  The turbine operates to a tank pressure of 75 lbf/in.², at which point the temperature is 450 R. Assuming the entire process is adiabatic, determine the turbine work. 

Answer 1

turbine & tank ⇒ Transient problem

Conservation of mass: m_i = m₂ = m
