Question 5Motor Plants - Assistant Engineer

The correct answer is B) 9,111 kW. To calculate the indicated horsepower (IHP) of the diesel engine, we can use the formula: IHP = (P x L x A x N x n) / (75 x 1000) Where: P = Mean Effective Pressure (MEP) in kg/cm^2 L = Stroke in meters A = Bore area in cm^2 N = Number of cylinders n = Revolutions per minute (RPM) Plugging in the given values: P = 30 kg/cm^2 L = 1.4 m A = π x (0.65 m)^2 / 4 = 3.32 m^2 N = 8 n = 100 RPM Calculating the IHP: IHP = (30 x 1.4 x 3.32 x 8 x 100) / (75 x 1000) IHP = 9,111 kW The other options are incorrect because they do not match the calculated value of 9,111 kW.
