Wаter аt 20∘C20^circtext{C} flоws frоm а tank thrоugh a 12 tfrac{1}{2} in commercial-steel pipe. The volumetric flow rate is Q=0.015 ft3/sQ = 0.015 text{ft}^3/text{s}The pipe length is L=105 ftL = 125 text{ft}For water at 20∘C20^circtext{C}, use ρ=1.94 slug/ft3,μ=2.09×10−5 slug/(ft.s)rho = 1.94 text{slug/ft}^3, qquad mu = 2.09times 10^{-5} text{slug/(ftcdot s)}For commercial steel, take ε=0.00015 ftvarepsilon = 0.00015 text{ft}Assume the tank is open to the atmosphere and determine the water surface elevation hhh needed to maintain the required flow rate. What level hh, in feet, must be maintained to deliver the required flow ?
