http://slidepdf.com/reader/full/oct-nov-oral-question 1/60

Fn4:

1) function of inducer in centrifugal pump

2) vertical centrifugal pump how is load on shaft taken care of.

3) whats the min temp at which centrifugal pump fails to take suction and y?

4)what determines power developed y engine.

!) "wo engines of same si#e kept covered how to $nd if its 2% or 4%..without openingor operation.

&) there's not drop of cylinder oil in the liner what provides initial lurication to the

liner..
