my friend the question u have asked is not complete .A petrol and diesel engine should be compared for a given parameter ,other wise how we can compare?.any way I am assuming that for same capacity.suppose consider a 1000CC petrol and diesel engine.Usually petrol will have more power becz,petrol engine produces more heat at the combustion chamber as petrol having more calorific value .moreover heat losses will be more in the cases of diesel engine than petrol engine such as compresion losses,turbulent loses,exhaust loses...Any way even though the compression ratio is high for diesel engine it wont contribute to increased power ,but an increased torque,thats why diesel engines have high torque than petrol engines for same capacity,still dobt existing mail me at bala300587@gmail.com

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
