When water flows from the tank shown in Fig. P8.58, the water depth in the tank as a function of time is as indicated. Determine the cross-sectional area of the tank. The total length of the 0.60-in.-diameter pipe is 20 ft, and the friction factor is 0.03. The loss coefficients are 0.50 for the entrance, 1.5 for each elbow, and 10 for the valve.
