V5 What is the water elevation in reservoir B given the following:

Elevation of reservoir A =2250m. The flow is 25m^3/sec. the temperature is 20C

there are two pipes in series with the following characteristics

D1 L1 D2 L2

2 m 1500m 1.6m 1000m

There are gate valves at the exiting and entering the reservoirs

There are two bends, 1 in each pipe size.There is is a globe valve on the downstream pipe.

What is the elevation of Reservoir B?

The water surface of the reservoir is at an elevation of 326 m.
A penstock with a length of 6.4 km supplies water
from the reservoir to a power plant at an elevation of 18m above
sea level. If the turbine inlet pressure is 2.4 MPa,
estimate the head losses in the penstock.

Water will be pumped from a reservoir free surface of which is
at an elevation of “z1” to reservoir the free water surface of
which is at “z2”. Both of the reservoirs’ free surfaces at
atmospheric pressures.Design a piping system that transmits water
from the lower reservoir to the upper reservoir at a volumetric
flow rate of Q (m3 /h).
Q = 200 (m3/h) Za = 10(m) Zb= 60 (m) Zc = 75 (m) L1=200 (m)

Water at 70°F flows by gravity from a large reservoir at a high
elevation to a smaller one through a 55-ft-long, 2-in-diameter cast
iron piping system that includes four standard flanged elbows, a
well-rounded entrance, a sharp-edged exit, and a fully open gate
valve. Taking the free surface of the lower reservoir as the
reference level, determine the elevation z1 of the higher reservoir
for a flow rate of 10 ft3/min. The density and dynamic viscosity of
water at 70°F...

Water flows at a rate of 30 ft3/s from a reservoir with elevation 45 ft to a lower one with elevation 0
ft through a pipe Of length 1800 ft with bends, elbows, entrances and exits contributing a total of
minor losses Of ?K = 2.5. The pipe has a roughness e = 0.0005ft.
-Determine the pipe diameter needed.
-How important are minor losses?
-Plot the EGL.

Consider a small Pelton wheel hydro turbine, with a total head
(reservoir surface to nozzle elevation difference) of Ht = 200 ft.
The flowrate to the turbine is 185 gal/s. If the pipe (penstock)
feeding the turbine has a length of 1000 ft, a diameter of 19.6 in,
and a friction factor of f = 0.005, determine the percent of total
head lost in the pipe (penstock). Submit your answer as a
percentage but without the percent symbol. ***NOTE: The...

A pump having the characteristics given in Fig. 14.10 pumps
water at 20°C from a reservoir at an elevation of 366 m to a
reservoir at an elevation of 450 m through a 36 cm steel pipe. If
the pipe is 610 m long, what will be the discharge through the
pipe?
