This problem needs repeated calculations. I would recommend you to use excel or Matlab to solve this problem. Set the calculations in a way you can just change the variables and get the results. Question: A pump will be used to deliver water from a river to a tank using the following system. The pump can be placed 10 m above the river water level and 5 m below the delivery end of the pipe. Given: L = 30 m L = 10 m L3 = 40 m 5 m Tank Elbow O Vahy Pump D = 0.05 m D2=0.15 m Dz = 0.1 m LI D 10 River Fitting loss constants: Kelbow = 0.69 Kexpansion = 0.5 Kcontraction = 0.5 Kvalve = 0.18 Kentrance = 0.05 Kexit=1.0 Density of water = 1000 kg/m3 Viscosity of water = 0.001 kg/m.s For the calculation of the friction factor, consider the pipes are smooth. Include the loss at the entrance and the exit in your calculation. a) Calculate the required power from the pump (as m-HO and horsepower) to deliver 475 gallon- per-minute (GPM). b) Repeat the calculation for 0, 50, 100, 200, 300, 400, and 500 gallon-per-minute (GPM) to find the required power as m-H20. All other variables remain same. Plot the required power from the pump (as m-H2O).vs. GPM. c) Repeat the calculation of part-a: for water-density of 1027 kg/m and 1050 kg/m (- seawater). All other variables remain same. d) Repeat the calculation of part-a: for water-viscosity of 0.0015 kg/m.s and 0.003 kg/m.s. All other variables remain same. e) Repeat the calculation of part-a: for 10% and 20% increase of the diameter of all the pipes. All other variables remain same
