Pump water from the well to the tank. Knowing the well is 4m deep, the pump is placed on the well mouth, the pump is 5m high from the tank, the total length of the pipeline is 20m. The diameter of the push pipe is equal to the diameter of the suction pipe 34, ignoring local friction, the coefficient of friction is equal to 0.013 The pump water flow is 2l/s. Calculate the total pressure of the pump to be overcome. Calculate the pump power given the pump efficiency is 0.7. Calculate the motor power knowing that the power supply is stable.​

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
