Question

A piston in a gas supply pump has an area of 500 cm and it moves a distance of 30cm during one stroke. The pump moves the gas against a fixed pressure of 4000Pa.How much work is done by the piston during one stroke​

Answer 1

Explanation:

A. 60 Joule

Explanation:

First find the force given the pressure and area.

F = AP

F = 500 cm² × (1 m / 100 cm)² × 4000 N/m²

F = 200 N

Now find the work:

W = Fd

W = 200 N × 30 cm × (1 m / 100 cm)

W = 60 J
