Question

A 2-cylinder C.I. engine with a compression ratio 13:1 and cylinder dimensions of $200\text{ mm} \times 250\text{ mm}$ works on two stroke cycle and consumes $14\text{ kg/h}$ of fuel while running at $300\text{ r.p.m.}$ The relative and mechanical efficiencies of engine are $65\%$ and $76\%$ respectively. The fuel injection is affected up to $5\%$ of stroke. If the calorific value of the fuel used is given as $41,800\text{ Kj/kg}$.Calculate the mean effective pressure developed.
