Consider the following parameters:
1. Impeller diameter
2. Fluid density
3. Speed
4. Type of casing
Head developed by a certrifugal pump depends on
For starting an axial flow pump, its delivery valve should be

If D is the diameter of impeller at inlet, B is the width of impeller at inlet and Vf the velocity of flow at inlet, then discharge through a centrifugal pump is equal to
When a piping system is made up primarily of vertical lift and very little pipe friction, the pump characteristics should be
In a centrifugal pump the inlet angle will be designed to have
A centrifugal pump has outer and inner diameters of 0.3 m and 0.15 m respectively. When running at 1800 rpm, with the discharge pipe completely shut off, the head produced is
[Take 0 = 1 0 m/s2]
If two pumps identical in all respects and each capable of delivery a discharge Q against a head Hare connected in parallel, the resulsting discharge is
