The average gas pressure on the piston in the tractor engine cylinder is 5,000,000 Pa, the piston stroke is 15.2 cm

The average gas pressure on the piston in the tractor engine cylinder is 5,000,000 Pa, the piston stroke is 15.2 cm, the area is 120 cm2. What is the work done per piston stroke?

To calculate the work of gases in the engine cylinder of the tractor used, we apply the formula: A = F * h = P * Sп * h.

Values of variables: P – average pressure on the piston (P = 5 * 10 ^ 6 Pa); Sп – area of the tractor piston (Sп = 120 cm2 = 120 * 10 ^ -4 m2); S is the length of the piston stroke (S = 15.2 cm = 0.152 m).

Let’s perform the calculation: A = P * Sp * h = 5 * 10 ^ 6 * 120 * 10 ^ -4 * 0.152 = 9.12 * 10 ^ 3 J = 9.12 kJ.

Answer: The work of gases in the tractor cylinder for one piston stroke is 9.12 kJ.
