Homework Help: Indicated Power (mechanics related problem)

  1. May 12, 2010 #1
    1. The problem statement, all variables and given/known data

    The Area of an air indicator card taken from one cylinder of a 7 cylinder two-stroke,
    single acting Diesel engine running at 75 r.p.m. is 2850 mm2 and the length is 75mm.
    The scale of the indicator spring is 0.2bar per mm height of Diagram. The bore of the
    cylinder is 800mm and stroke of the piston is 1850mm.
    Calculate the indicated power.

    2. Relevant equations

    Power = mean effective pressure x lenght of stoke x cross sectional area of cylider (diameter=bore) x revolutions per second

    mean effective pressure (m.e.p) = average height x spring constant

    3. The attempt at a solution
