The following are the data obtained in a stream- gauging operation. A current meter with calibration equation V=( 0.32N+0.032)m/s, where N= revolutions per second was used to measure the velocity at 0.6 depth. Calculate the discharge in the stream.

1. The performance data of a water pump follow the curve fit Havailable =Ho +aV, where the pump's shutoff head Ho="K", coefficient a="Y" m/(Lpm)?, the units of pump head H are meters, and the units of Vare liters per minute (Lpm). The pump is used to pump water from one large reservoir to another large reservoir at a higher elevation. The free surfaces of both reservoirs are exposed to atmospheric pressure. The system curve simplifies to Hrequired =(Z2-Z1)+bV², where elevation difference z2-z1="X" m, and coefficient b = "L" m(Lpm)?. Calculate the operating point of the pump (a) V. operating and (b) Hoperating) in appropriate units (Lpm and meters, respectively). Read the equation carefully. (Zz-Z:) Но b a Y K L 0.0479 4.9 0.029
