Problem-Solving: Solve the problem below. For your final answers, use 2 decimal places.
A test of a single-cylinder, 318 mm x 330 mm single-acting, two-stroke cycle diesel engine resulted in the following data:
Engine speed: 350 rpm
Net load on brake arm: 632 N
Brake arm: 1.28 m
Length of all cards: 7.52 cm
Ave area of indicator card from working cylinder: 2.568 cm$^2$ (spring scale is 950 kPa/cm)
Ave area of indicator card from crankcase: 3.162 cm$^2$ (spring scale is 32.62 kPa/cm)
Determine the following:
1. Indicated Mean Effective Pressure in kPa
2. Indicated Power in kW
3. Brake Power in kW
4. Friction Power in kW
5. Mechanical Efficiency
