A group of engineers is designing a new hydroturbine by scaling up an existing one. The existing turbine (turbine A) has diameter DA = 1.50 m, and spins at n.A = 150 rpm. At its best efficiency point, V.A = 162 m3 /s, HA = 90.0 m of water, and bhpA = 132 MW. The new turbine (turbine B) will spin at 120 rpm, and its net head will be HB = 110 m.
