A pump increases the water pressure from 100 kPa at the inlet to 900 kPa at the outlet. Water enters this pump at 15 degree C through a 1-cm-diameter opening and exits through a 1.5-cm-diameter opening. Determine the velocity of the water at the inlet and outlet when the mass flow rate through the pump is 0.5 kg/s. Will these velocities change significantly if the inlet temperature is raised to 40 degree C?

(5 pts) A pump is pumping water from a lake to the top of a mountain through a constant- diameter pipe. Water exits the pipe at a volumetric flow rate of 0.04 m/s. The vertical distance between the lake surface and the pipe exit at the top of the mountain is 100 m. The diameter of the pipe is 10 cm. All mechanical energy losses are negligible and the flow is steady and incompressible. (Water density-I g/cm, ?-I.) Determine a)...

Question 4 Liquid water enters a feedwater heater at inlet 1 with inlet conditions 15 MPa, 40°C at 60 kg/s. Another stream of water in saturated mixture enters the heater at inlet 2 at temperature of 175 °C. The heater operates at steady state and heat transfer to surrounding can be neglected. At exit 3, saturated liquid flows out at 275 kPa. Select two (2) different values of mixture quality at inlet 2 between 0.5 and 0.8, and subsequently plot...
