The 1-m-long, tube-within-a-tube, heat exchanger shown in the sketch is used to condense steam at 2 atm in the annulus. Water flows in the inner tube, entering at 90°C. The inner tube is made of copper with a 1.27-cm-OD and 1.0-cm-ID.

(a) Estimate the water flow rate required to keep its outlet temperature below 100°C.

(b) Estimate the pressure drop and the pumping power for the water in the heat exchanger, neglecting inlet and outlet losses.
