A pump at an elevation of 300m is pumping 0.05 m³/s of water through 2.4 km of 150-mm pipe to a reservoir whose level is at an elevation of 380m. What pressure will be found in the pipe at a point where the elevation is 335m above the datum and the distance (measured along the pipe) from the pipe is 970m? Compute the capacity of the pump. Use E/D= 1.5384x10-³
A pump draws water from reservoir A and lifts it to reservoir B as shown. The head loss from A to 1 is three times the velocity head in the 150-mm diameter pipe and the head loss from 2 to B is twenty-five times the velocity head in the 100-mm diameter pipe. The discharge in the pipe is 20 liters/second. Find the power delivered by the pump in kW. Calculate the pressure head at point 1 in meters. Solve the pressure head at point 2 in meters.

The diameter of the pipe at the larger end is 0.50 cm and at the smaller end is 0.20 cm, the larger and smaller ends located 7 meters and 3 meters respectively, from the datum line. If the larger end, the velocity is 1.2 m/s and the pressure is 5200 kN/m2 , compute the velocity at the smaller end.
A pump draws water from reservoir A and lifts it to reservoir B as shown in figure 4. Elev. of water at reservoir A is 10m.The loss of head from A to 1 is 3 times the velocity head in the 150mm pipe and the loss of head from 2 to B is 20 times the velocity head in the 100mm pipe.

A pipe has an initial radius of r1, which then changes to a radius of r2. The velocity of the water in the initial part of the pipe is v1. The segment of the pipe with the smaller radius is also 0.5 m higher than the initial pipe segment. What is the pressure difference between the two parts of the pipe? let r1=10cm let r2=6cm let v1=5m/s b) What is the volume flow rate in the pipe?
The task is to to transfer the fluid from the source towards the tank (TANK A) lying on an elevated platform as shown. The goal is to fill up that 16.49 m by 2.23 m by 6.36 m tank (TANK A) within 11.5 mins (from empty to full). Your budget is limited to 605,000 pesos. Head loss on pipe due to friction is 1.23 meters per 1 meter of pipe. Because it's Fluid Machinery and not Engineering Economics, it's ok for your design to exceed the budget BUT YOU HAVE TO JUSTIFY IT. The pictures I will post is the guide to answer Its okay if the answer is computerized

A 75 mm diameter fire hose discharges water through a nozzle having a jet diameter of 25 mm. The lost head in the nozzle is 25% of the velocity head in the jet. If the pressure at the base of the nozzle is 625 KPa: compute the discharge in m3/min; the maximum horizontal range to which the stream can be thrown; the maximum vertical reach, and the diameter of the jet at a point two-third of the maximum vertical reach from the tip of the nozzle. Neglect air resistance
3. In the following system, the flow rate of Q= 400 It/s is transmitted from the A chamber to the B chamber. There is a valve in the pipe where the diameter is large and there is a local loss due to the valve. Using the valve formula (K) as 10 (see formulas), calculate the distance H between the water face elevations of the two chambers. Draw the relative energy and piezometer lines.
