A pump delivers 0.0157 m3/s of water from one reservoir to a second with a surface level 30.5 m above first. The pipe is 150m diameter for 1.2 km and changes to 100mm diameter for the remaining 0.4 km. The resistance coefficient is 0.009. Neglecting losses other than due to pipe friction, find the power required to drive the pump if it has an efficiency of 0.7.
The question belongs to Chemistry and it discusses about calculating the power required to drive the pump with an efficiency of 0.7. This has been discussed in the solution detail.
