Question

Problem 133. When the crank is 45° from the inner denj centre on the down stroke, the effective steam pressure on the ilon of a vertical steam engine is 2-5 bar. The diameter of the clinde, = 75 cm, 8troke of the piston-50 cm, length of th = 100 cm. Determine the torque on the crank shaft, if the engine runs at 350 r.p.m. and the mass of reciprocating parts is 200 kg.
