a centrifugal pump has a casing,an impeller mounted on a shaft,an inlet and an outlet pipe.the shaft is connected to a motor,which causes the impeller to rotate.this produces a low pressure area at the eye of the impeller(the center of the impeller).the pressure difference causes the fluid to be sucked up into the casing.the curved vanes of the impeller rotates the fluid,imparting kinetic energy to the fluid due centrifugal force(hence the name centrifugal pump).energy is imparted to the fluid by this means.this fluid now enters the volute,which is a part whose cross sectional area increases gradually.as per Bernoulli's law and equation of continuity, the velocity decreases as the area of cross section decrease.the drop this kinetic energy is compensated by an increase of pressure energy(pressure head),which can be used to transport the liquid to a greater height.basically,a pressure difference between the inlet and the reservoir sucks the fluid into the casing,and the energy imparted in the form of kinetic energy is converted to pressure 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
