Question

A V12, 4 stroke, normally aspirated piston engine develops a brake mean effective
pressure of 14atm, having a piston stroke of 130mm, a cylinder bore of 140mm and operates at
3000rpm in sea-level-standard ambient conditions. The internal efficiency is 73% and the charge
mass flow is 0.4kgs-1. Find a) The Brake Power b) The Indicated Power c) The indicated mean
effective pressure d) The volumetric efficiency ηv (Air density at sea level standard = 1.225kgm-3)
