(a) What is the value of the physical head height of a 515 MW hydrolectric installation where a Pelton turbine is supplied at a flow rate of 20.8 m3s by a 512 m penstock with a calibration of 0.91 m of head loss per 100 m length? Assume the Pelton turbine is 97% efficient, the acceleration due to gravity is 9.8 ms-2 and the density of water to be 1000 kgm-3.
