how a centrifugal pump is working?
Answer Posted / sunil kumar singh
A centrifugal pump is one of the simplest pieces of
equipment in any process plant. Its purpose is to convert
energy of a prime mover (a electric motor or turbine) first
into velocity or kinetic energy and then into pressure
energy of a fluid that is being pumped. The energy changes
occur by virtue of two main parts of the pump, the impeller
and the volute or diffuser. The impeller is the rotating
part that converts driver energy into the kinetic energy.
The volute or diffuser is the stationary part that converts
the kinetic energy into pressure energy.
Note: All of the forms of energy involved in a liquid flow
system are expressed in terms of feet of liquid i.e. head.

2. Dry saturated steam at 3.5 bar is expanded through a convergent nozzle to 2.2 bar. The exit area is 5 sq. cm. Calculate the exit velocity and mass flow rate, assuming isentropic expansion and super saturated flow. b) A cast iron cylinder head is fastened to a cylinder of 750mm bore with 12 stud bolts. The maximum pressure inside the cylinder is 3 Mpa. The stiffness of part is thrice the stiffness of the bolt. What should be the initial tightening load so that the point is leak proof at maximum pressure? Also choose a suitable bolt for the above application 2 The propeller shaft of a marine engine is to transmit 600 kW at 1200 rpm, without a significant bending. The efficiency of the propeller is 88% at 32 knots ( 1 knot = 1085 km/hr). If the slenderness ratio is less than 50 and the permissible shear stress should not exceed 65 Mpa. Determine the diameter of shaft. 3 A semi-elliptic leaf spring consists of two extra full-length leaves and six graduated length leaves, including the master leaf. Each leaf is 7.2 mm thick and 65 mm wide. The centre-to-centre distance between the two eyes is 1.3m. The leaves are pre-stressed in such a way that when the load is maximum, stress induced in all leaves are equal to 380 N/mm sq. Determine the maximum force that the spring can withstand
