An engine $200$ mm diameter and $300$mm stroke length works on diesel cycle.

The initial pressure and temperature are $1$bar and $270$C$.$ The cutoff is $8\%$ of the

stroke and the compression ratio is $15.$ Find $($i$)$ pressure and temperature at all

salient points of the cycle $($ii$)$ theoretical air standard efficiency $($iii$)$ MEP $($iv$)$

power developed if there are $400$ working strokes per cycle.
