PLEASE GUYS BE SERIOUS.I WANT RESULT OF THIS QUESTION NO COPY PASTING THE USELESS ANSWER HERE.PLS DO IT BY STEP BY STEP.

1) The topography of a new subdivision varies from 85 m to 105 m RL. A service reservoir with top water level (TWL) and bottom water level (BWL) of 147 m RL and 142 m RL respectively will service the subdivision. A minimum residual head of 22 m is required in the reticulation system, and the distribution main should have a peak hour (PH) capacity.

a) What is the required minimum design head for the distribution main? Give the answer in meters.

b) A consultants report recommends the construction of a 300 mm (331 mm internal diameter) 6 km length ductile iron distribution main from the service reservoir to the subdivision. What is the flow rate of distribution main in ML/d, based on the minimum available design head? Minor losses are negligible and can be ignored. The pipe wall roughness is 0.03 mm. Show clearly the steps and calculations. Give the answer in 2 decimal places

c) Assuming the average demand (AD) is equal to 250 L per person per day and PH equals to four times AD, then how many people will be served by this trunk? Give the answer in whole number

d) If the current and future population is expected to be 7000 and 10000 respectively, comment on the shortfall and excess of population served. Suggest two immediate measures you will be taking to address any inadequacies supported with calculations.
