An orifice meter is used to measure flow rate of liquid in pipe
shows a pressure difference of ' x ' m of water column when the
flow rate is Q If flow rate is doubled then what is delta P?
A 75‐mm‐diameter orifice with D and D/2 taps is used to measure
the flow rate of 65°C water in a 150‐mm‐ID pipe. Determine the
pressure difference for a flow rate of 20 L/s
how does the rotameter (flow meter) measure volumetric flow rate
of air in the system?explain using a digram and 2-3 sentence
discussion of the forces acting on the rotameter ball.
A pipe is carrying liquid at 60 degrees C, that fluctuates in
pressure from 0 to 60,000 kPa (non-capped). The inside diameter of
the pipe is 20 mm and the wall thickness is 1 mm and is made out of
1095 carbon steel, has a yield strength of 813 MPa and an ultimate
tensile strength of 1260 MPa. Using the "Modified-Goodman" failure
criteria and a reliability factor of 99%, determine the number of
cycles till failure on the inside wall....
6. An increase in roughness of a pipe with laminar flow would
increase the pressure drop of the pipe. Assume the velocity is the
same for the smooth pipe and the rough pipe.
a. True
b. False
A 90o v-notch weir is used to measure discharge flow rate. A
head (H) of 6 inches is measured behind the weir. Assume the
following:
Weir equation is Q = 2.5H2.5 (Q in cfs and H in feet)
1 cfs = 450 gpm
a) Estimate discharge flow rate in gallons per minute (gpm)
b) Briefly describe hydraulic principle of open channel flow

Water moves through a constricted pipe in steady, ideal flow.
The pressure is 1.80 ✕ 105 Pa and the pipe radius is 2.90 cm. At
the higher point located at y = 2.50 m, the pressure is 1.30 ✕ 105
Pa and the pipe radius is 1.60 cm.
(a) Find the speed of flow in the lower section.

(b) Find the speed of flow in the upper section.
m/s
(c) Find the volume flow rate through the pipe.

Saturated liquid water at 1 MPa enters a D = 5 cm pipe at a rate
of m(dot) = 2 kg/s. Heat is transferred to the water at a rate of
Q(dot) = 5000 kW. The exit is at 1 MPa pressure.
(a) Neglecting kinetic energy, calculate the temperature at the
pipe exit. (ans = 400◦C)
(b) Using your answer in a), calculate the exit velocity of the
water. (ans = 312 m/s)
(c) Based upon your answer, should kinetic...
Find the diameter of a pipe of length ‘X’ when the rate of flow
of water through the pipe is ‘Q’ and the head lost due to friction
is ‘4X’. Take the value of C = 1 in Chezy’s formula. Illustrate the
resut of diameter of pipe and also conclude the discharge value for
varying cross section of pipe, and the relationship between
diameter of pipe and pressure of flow.
The pressure drop per unit length of a pipe, dl/dp , for steady,
incompressible viscous flow through a straight horizontal pipe
depends on the average velocity, V, density of fluid, p, fluid
viscosity, µ, pipe diameter, D, and the roughness height, ks.
Determine the dimensionless groups that can be used to correlate
the data.
