Please answer the following questions.
1. does a centrifugal pump work on the positive displacement
pronciple?
2. in laminar flow through a pipe, is the velocity profile
linear across the diameter?
3. Are friction losses in a pipe independent of the roughness
of the pipe at large reynolds numbers?
4. Does the fanning friction factor have unita of shear force
per unit wall surface area of pipe?

Toledo Pump Company manufactures two different types of
pumps: centrifugal and displacement. The Company uses an
activity-based costing system to allocate production overhead
costs. The following are the estimated cost data for the
period.
The number of units to be produced during the period are
Centrifugal 1,800 units; Displacement 1,200
units.
Raw materials and direct labor costs per unit are as
follows:

1. Oil with a specific gravity of 0.75 is pumped by a
centrifugal pump at 375 gpm, 19 hp, and 81% efficiency. Determine
the pressure head in terms of: a) Feet of oil b) Feet of water
answers: a) 217 ft b) 162 ft

2. A centrifugal pump running at 750 rpm with a 1-m-diameter
impeller generates
the following pressure rise and flow rate data while pumping
water at room temperature:
?(dot)[m^3/s]= [0, 0.0278, 0.0417, 0.0556, 0.0694, 0.0833,
0.0903, 0.0972]
?P [kPa]= [361, 349, 328, 293, 230, 145, 114, 59]
Estimate the pressure rise and flow rate for impeller speeds of
500 and 1000 rpm using the 750 rpm data. Plot pressure rise
(y-axis) vs flow rate (x-axis) for all three pump speeds and...

1. A centrifugal water pump impeller is given an inlet and exit
radius of 400 mm and 1200 mm, and an inlet and exit blade thickness
of 120 mm and 80 mm. The entering and exiting blade angles are 40o
and 60o respectively. If the pump rotational speed is 575 rpm with
and efficiency of 85%, determine: a) Ideal head (m) b) Fluid power
for max pressure (kW) c) Shaft torque for max pressure (Nm)
solutions a) 488 m b)...

1. The impeller in a centrifugal pump has inner diameter as
125 mm and outer diameter as 270 mm. The pump runs at 1400 rpm. The
vane angles of impeller at inlet and outlet are 17° and 30°
respectively. The water enters the impeller radially and velocity
of flow is constant. Determine the work done by impeller per unit
weight of water.

CASE STUDY ON AGENCY PROBLEM ABC
Company started operations in early 1970. The company produces
specialized items for manufacturing cars. Most of the raw materials
used are imported from Brazil because the cost is low and the labor
is very cheap. The CEO for ABC Company, Mr. Rodriguez, makes...

Required water flow rate varies from 500 m3/h to 700 m3/h. For
the pump to deliver 550 m3/h, the flowrate has been reduced by
partially closing the delivery valve. Motor efficiency is 93%.
