2. Water at 70°F flows by gravity from a large reser-voir at a high elevation to a smaller one through a 60-ft-long, 2-in-diameter cast iron piping system that includes four stand-ard 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 ele-vation z1 of the higher reservoir for a flow rate of 10 ft3/min.
