Methanol is to be pumped from large storage to tank cars at the rate of 1000 litres per min. The transfer line is 10 cm internal diameter and consists of 150m of straight pipe, four 900 standard elbows (Le/D =32) two side run tees (Le/D = 90) and two gate valves (Le/D = 7). The level in the storage tank is 5 m below the level of the discharge. If a centrifugal pump having an overall efficiency is 70 % is used for this purpose, determine the horse power needed
Data
Density of methanol = 0.79 gm/cc
Viscosity of methanol = 0.66 c.p
Fanning’s friction factor may be calculate from the relation, f = 0.08 Re-0.25

Water at 200 Fahrenheit is pumped from a storage tank at the
rate of 50 gallons/minute. The motor for the pump supplies work at
the rate of 2 hp. The water goes through a heat exchanger, giving
up heat at the rate of 40,000 BTU/minute(Q Net In), and is
delivered to a second storage tank at an elevation 50 feet above
the first tank. What is the temperature of the water delivered to
the second tank?

A large storage tank with an open top is filled to a height h0.
The tank is punctured at a height h above the bottom of the tank.
Find an expression for how far from the tank the exiting stream
lands. (Let d be the horizontal distance the stream of water
travels. Use any variable or symbol stated above as necessary. ?
for the density of water and g. Do not substitute numerical values;
use variables only.)

Octane is to be pumped in a piping system that is routed from
storage tanks to the main pump by a number of smaller pumps. One
such arrangement is shown below. This pump must supply 0.4 m3 /s of
octane to the main pump. All fittings are flanged; the pipe is
wrought iron, schedule 80, 2 nominal, with L=65 m. The absolute
pressure at section 2 is 282.5 kPa. Determine the power required to
be transferred to the liquid. Assuming...

Beer is to be pumped from a fermenting vessel to a racking tank
at a velocity of 1.5 m/s through a 100 mm ID pipe, having an
absolute roughness of 0.05 mm. The total length of the pipe,
allowed for fitting and valves is equivalent to 10 m on the suction
side of the pump and 60 m on the delivery. The pump is situated at
3 m below the constant level of beer in the fermenting vessel,
which is...

A large storage tank, open to the atmosphere at the top and
filled with water, develops a small hole in its side at a point
11.6 m below the water level. Assume the tank is large so the
velocity of the water at the top of the tank is zero. The rate of
flow from the leak is 2.53×10−3 m3/min.
(a) Determine the speed at which the water leaves the hole.
(b) Determine the diameter of the hole (in millimeters)....

Water is being pumped into a leaky inverted conical tank at a
rate of 10 m^3/h. The tank has a height of 9 m and the diameter at
the top is 6 m. If the water level is rising at a rate of 0.2 m/h
when the height of the water is 6 m, how fast is the water leaking
out at that time?
