Water at 70°f flows by gravity from a large reservoir at a high elevation to a smaller one through a 66-ft-long, 2-in-diameter cast iron piping system that includes four standard flanged elbows, a well-rounded entrance, a sharp-edged exit, and a fully open gate valve. taking the free surface of the lower reservoir as the reference level, determine the elevation z1 of the higher reservoir for a flow rate of 10 ft3/min. the density and dynamic viscosity of water at 70°f are rho = 62.30 lbm/ft3 and μ = 2.360 lbm/ft·h = 6.556 × 10–4 lbm/ft·s. the roughness of cast iron pipe is ε = 0.00085 ft.(round the final answer to one decimal place.)
