Apump is required to pipe water from a well 7.0m in depth to an open-topped water tank at ground level. the pipe at the top of the pump, where the water pours into the water tank, is 2.00cm in diameter. the water flow in the pipe is 5.00m/s.
what is the kinetic energy density of the water flow?
what pressure is required at the bottom of the well? (assume no energy is lost – i. e., that the fluid is traveling smoothly.)
what power is being delivered to the water by the pump? (hint: for the next part, refer to chapter 12)
if the pump has an efficiency of 45%, what is the pump’s electrical power consumption?
if the pump is operating on a 220v power supply (typical for large pieces of equipment like this), how much electrical current does the pump draw?
at 13.5 cents per kilowatt-hour, how much does it cost to operate this pump for a month if it is running 5% of the time?

Asteel tube (k=50 w/mk) of inner and outer diameter di = 20mm and do=26mm, respectively, is used to transfer heat from hot gases flowing over the tube (h-hot = 200w/m2k) to cold water flowing through the tube (h-cold = 8000 w/m2k). what is the cold-side overall heat transfer coefficient uc? to enhance heat transfer 16 straight fins of rectangular profile are installed longitudinally along the outer surface of the tube. the fins are equally spaced around the circumference of the tube, each having a thickness of 2mm and a length of 15mm. what is the corresponding overall heat transfer coefficient uc? *solve for uc in both cases*
