1. In a geothermal power plant, the used geothermal water at 80°C enters a 15-cm-diamete and 400-m-long uninsulated pipe at a rate of 8.5 kg/s and leaves at 70°C before being reinjected back to the ground. Windy air at 15°C flows normal to the pipe. Determine the average wind velocity [km/hr]. Assume that the pipe surface temperature is equal to the water temperature and that radiation heat transfer can be neglected.

***Solve the following problems, correctly and systematically, and show all the necessary figures. Show your complete solutions neatly. Thank you!*** A single-stage centrifugal pump having a suction pipe 254 mm in diameter and a discharge pipe diameter of 5 inches is being tested and found to discharge 48 lps of water. A pressure gage connected to the inlet pipe reads 118 mm Hg vacuum and a discharge gage reads 150 kPa at a distance 100 cm above the point where the inlet pressure was measured. If the kW rating of the driving motor is 12 kW, calculate: a) the pump efficiency. b) if this pump runs at 1800 rpm, what will be the new discharge rate, head, and power developed if the pump speed was increased to 3600 rpm? Assume constant efficiency. c) Determine the pump type.
