To find the actualwater flow rate the no load flow is subtracted from Q using a sum block. Using the signal Qand 1/G and a product block, a new signal Q/G is produced, the square root of which gives theactual value of head, H according to Equation 15. Turbine frictional factor is neglected in thismodelling. To get the value of Pm, Equation 16 ...
