A nine-cylinder radial aircraft engine has a bore of 5.5 inches and a stroke of 5.5 inches and runs at 3500 rpm. Assuming that the brake horsepower of the engine is measured at 600 hp, calculate the brake mean effective pressure (BMEP) the indicated mean effective pressure (IMEP) (hint: assume an appropriate value for ηmech).

= 85%![\eta mech = \frac{[BMEP]}{[IMEP]} *100](/tpl/images/0626/6116/97050.png)
![B MEP =[ \frac{60 *10^{3} E }{s * a * n * w} ]](/tpl/images/0626/6116/06934.png)
![85 = \frac{[398154. 542]}{[IMEP]} *100](/tpl/images/0626/6116/e0b1d.png)
