Question

A piston/cylinder arrangement B is connected to a 1-m³ tank A by a line and valve, Initially both contain water, with A at 100 kPa, saturated vapor and B at 400°C, 300 kPa, 1 m³. The valve is now opened and, the water in both A and B comes to a uniform state. a. Find the initial mass in A and B. b. If the process results in T₂ = 200°C, find the heat transfer and work. 

Answer 1

C.V.: A + B. This is a control mass.

Continuity equation: m₂ - (m_A1 + m_B1) = 0 ;
