Ans a) Pressure head = P / g
Velocity head = V2 /2g
Datum head = z
Since, all points are at equal elevation , datum head ,z = 0
Ans (c) The EGL and HGL are curved due to sudden change in pressure and velocity head due to expansion and contraction of pipe in which fluid is flowing .

A reservoir A connected to B reservoir through a pipe that is 5 km long and 230 mm in diameter. The difference in water level of the two reservoirs is 70 m. At a distance of 2 km from the feeder reservoir, water is drawn at the rate of 40 litres/s .

(b) Water flows under gravity through a pipeline connecting two reservoirs as shown in Figure 2. The pipeline consists of 2 km of pipe diameter 400 mm and sand roughness equivalent 0.03 mm followed by an abrupt change to 3 km of 500 mm diameter pipe of sand roughness equivalent 0.08 mm. The pipe discharges as a free jet into a reservoir. The difference in elevation between the water surface of the upstream reservoir and the discharging jet is 21...

An orifice meter with a 2 inch diameter opening is used to measure the flow rate of water through a horizontal 3 inch diameter pipe. A mercury manometer is used to measure the pressure difference across the orifice. If the differential height of the manometer is 7 inches, determine the volumetric flowrate (gal/min) of water through the pipe. You may assume the discharge coefficient is 0.6.
1. A pipeline with a pump from Tank A leads to a nozzle that discharges by cascade into Tank B. Tank 8 is located 10 ft above Tank A. What is the flow rate when the pump adds a head of 80 ft. Assume the head loss in the 6 ft suction pipe can be described by hy-5V-/2g, while the head loss in the 4 inch pipe can be described by 12V?/2g. Sketch the hydraulic grade line and the energy...
A flow rate meter is used to measure the flow rate of a water flow from left to right) in an inclined position. Due to spatial confinement, the two pressure taps-manometer tubes were inclined as well as shown. The meter is similar to a Venturi meter except at the small pipe the pressure tap is a stagnation pressure tap at 2. For the given geometries, calculate: 1) (4 pts)The velocity at the large pipe, in m/s 2) (3 pts)The velocity...

For the systenm shown n the figure below 1. Determine the power that the pump must supply to the fluid i order to maintain the flow rate, specify your answer in Horsepower 2. State how much power must be...
Problem 3 A pipeline delivers water from Reservoir 1 to Reservoir 2 as shown in the following figure. The water levels at Reservoirs 1 and 2 are 50 ft and 20 ft, respectively. A globe valve is installed in the pipeline with a minor head loss coefficient k 10. The pipe from Reservoir 1 to the globe valve is 1000 ft long and 6 inches in diameter. The pipe from the globe valve to Reservoir 2 is also 1000 ft...
