Steam moves into a cylinder of a steam engine at a constant pressure and does 2.34 J of work on a piston. The diameter of the piston is 3.4 cm and the piston travels 4.6cm. What is the pressure of the steam?

Respuesta :

We are given with
W = 2.34 J
D = 3.4 cm
L = 4.6 cm

To get the pressure of the steam we use the formula
W = P
ΔV
2.36 J = P π (3.4 x 10-2)²/4 (4.6 x 10-2)
P =  56508 Pa
