b. Two cylinders are filled with liquid water (p = 998 kg/m³), and connected by a pipe line with a closed valve. Cylinders A (inside diameter = 42.75 cm) and B (inside diameter = 55 cm) contain 125 kg and 450 kg of water, respectively. The height h as indicated in Fig. 3 is 0.85 m. Determine the pressure (in kPa) of cylinder A and cylinder B on either side of the valve. If the valve is opened such that water flows to an equilibrium between the two cylinders, find the final pressure (in atm) at the valve location. Assume Po= 100 kPa. k Po B g Figure 3 Po A

0.56 kg of water in a piston cylinder device as shown initially the water is at T, = 120 °C with volume V, = 36 L (State 1). Heat is then added such that all the water in the cylinder is saturated vapor and the piston just touched the spring without exerted any force on the spring (State 2). Then additional heat is added to the system such that the temperature is T, 600 °C and the pressure is P,= 400 kPa (State 3). 3 Po 3 1) Find the total work (from state 1 to state 3, in kW).
