A centrifugal pump lifts 100 l / s of a liquid against a net head of 150 kPa. The brake power required is 18.0 kW when the liquid is water with a specific weight of 9.8 kN / m3. What would be the brake power if the liquid is a solvent having a relative density of 0.8 instead of water, with all other factors remaining the same as before?
