A centrifugal pump is used to elevate toluene (ρ = 867 kg/m3) from Tank 1 situated at  10 m from ground to Tank 2 (a much larger tank) at 22 m from ground. The toluene is to be supplied from a pressurized tank at 1.25 atm to a closed tank maintained at atmospheric pressure. The efficiency of the pump is given as 65% and the toluene is transferred in the standard steel pipes (1.0 NPS with SCH. No. 80). The mass transfer rate is measured at 12,000 kg/h. Calculate:  (i) The developed head, ΔH between the inlet and the outlet stream.  (ii) The work done by the pump, Wp  (iii) The total power input, PB  (iv) The power transferred to the fluid, Pf
