2. Water at 21°C enters a pump as a saturated liquid with a volumetric flow rate of 0.3
m/min through an inlet pipe with a 15 cm diameter. The pump is at steady state and
supplies liquid water to two exit pipes having diameters of 6 and 9 cm. The mass flow
rate in the 6 cm pipe is 1.5 lbm/s, and the temperature of the water exiting each pipe is
23°C. Determine the water velocity in each of the exit pipes (m/s).

At the inlet of the pipe, the water is in a saturated liquid state at 2 bar pressure. After the water in the pipe interacts with the heat engine, the water is in the form of a saturated gas at 2 bar pressure at the outlet of the pipe. The heat pump can only obtain energy from a reservoir at 16 ℃. Engineers have calculated that 25kW of power must be transferred to the heat engine for this process to take place.
