; ρair = 1.2 kg/m3
; g = 9.8 m/s2 

EB, loop. Water is pumped in a closed loop of total length L = 40m and constant pipe area A = 0.01 m². The pump performance is given as head versus flow rate: h₂ = 10-1000 Q², and the total piping system friction head loss is given as h₁ = 4 V²/g, where Q is flow rate and V is the water velocity in the pipe. (a) Find the flow rate? ;(b) Find the required pump power; (c) Find the Ap increase above the pump, Ap = P2-p₁. Assume the pump is 100% efficient - no friction losses inside the pump. Ans OM: (a)Q: 10² m³/s; (b)Wp: 10⁰ kW; (c)AP: 10¹ kPa
