Question

answer for c and d

 

You are asked to explore the operating principles and efficiencies of hydraulic machines. You have a pump-turbine system, which is a system that is used by some power plants for energy storage by pumping water during periods of low demand and for electricity generation during periods of high demand. You are required to: A) Determine the input power required for a pump that is attached to the end of a pipeline with a height of 40 m to pump water into the storage tank at a volumetric flow rate of 0.01 m³/s if its efficiency is 70 %. B) Calculate the efficiency of a water turbine if the available head at the turbine inlet is 30 m, the mass flow rate is 100 kg/s, and the output electricity is 25 kW. C) Identify the types of water turbines and the limitations that exist within these different types? D) From your external reading and point of view, discuss the ecological impact of hydroelectric power then suggest remedies for solving this issue?
