The crank-pin circle radius of a horizontal engine is 300 mm. The mass of the reciprocating parts is 250 kg. When the crank has travelled 30° from T.D.C., the difference between the driving and the back pressures is 0.45 N/mm^2. The connecting rod length between centres is 1.2 m and the cylinder bore is 0.5 m. If the engine runs at 250 r.p.m. and if the effect of piston rod diameter is neglected, calculate the net load on piston.

Fred · Answer 1 · 2022-10-16T11:10:29+0000

Right answer is (a) 5.715

To explain I would say: The brake power of an engine is given by the relation:

B.P = [(W-S)π (D+d)N]/60

= 5715 W.

Flywheel diameter 1.2 m; diameter of the rope 12.5 mm; engine speed 200 r.p.m.; dead load on the brake 600 N; spring balance reading 150 N. Using this data, calculate the brake power of the engine in kW.
