Assuming a cost of AED 1.5/Liter to pump and distribute water in a municipal supply system that loses (P) of its water because of leaks, how much money is wasted annually for a city of (X) million people with a per capita demand of 300 Liters/day?

where, X = 21.0 millions P = 2%

Solutions

Expert Solution

Detailed answer is as follows

First let us calculate the water requirement per day based on the given date.

Total demand/day

Population =21000,000

Per capita demand = 300 litres/day

Total demand =21000,000 x 300

                    =6300,000,000 litres

Wastage per day

Percentage of wastage is 2%

Per day wastage in litres = (2/100) x 6300000000

                                      =126,000,000 litres

Money wasted per year

Money wasted per year =wastage per day x 360 x rate per liter

                                   =126,000,000 x 360 x 1.5

                                   =AED 68,040,000,000

A pump operating at steady state receives 1.5 kg/s of liquid water at 50oC, 1.5 MPa. The pressure of the water at the pump exit is 14 MPa. The magnitude of the work required by the pump is 25.2 kW. Stray heat transfer and changes in kinetic and potential energy are negligible. Determine the work required by a reversible pump operating with the same conditions, in kW, and the isentropic pump efficiency.
