A 1,200-mm diameter transmission pipe carries 126 l/s from an elevated storage tank with a water surface elevation of 540 m. Two kilometers from the tank, at an elevation of 434 m, a pressure meter reads 586 kPa. If there are no pumps between the tank and the meterlocation, what is the rate of head loss in the pipe? (Note: 1 kPa = 1,000 N/m2.)

Hydrodynamics pumps (WRITTEN COMPLETE SOLUTION AND FIGURES IF NEEDED) 1. A centrifugal pump installation draws water from an open reservoir having a water elevation of 5 m above the pump centerline and delivers the water to another open reservoir 80 m above pump centerline. The rate of discharge is 600 li/min. The suction pipe has a diameter of 200 mm while that of the discharge pipe diameter is 150 mm. The friction loss at the suction is estimated to be 4 times the velocity head at the 200 mm suction pipe. At the discharge, the friction loss is estimated to be 21 times the velocity head at the 150 mm discharge pipe. If the overall mechanical efficiency is 77%, estimate the brake power input to thepump.  a. brake power Answer : ____________________ kW

A venturimeter having a throat diameter of 0.1 m is used to estimate the flow rate of a horizontal pipe having a diameter of 0.2 m. For an observed pressure difference of 2 m of water head and coefficient of discharge equal to unity, assuming that the energy losses are negligible, the flow rate (in m3/s) through the pipe is approximately equal to

Water is flowing in a 3 m wide rectangular channel. A hydraulic jump occurs and the flow upstream is 360 mm deep while the flow downstream from the jump is 1300 mm deep. A) Find the discharge flowing in the channel. B) Find the energy absorbed by the jump in kW. Please answer correctly
