Pressures up to 3000(atm) are measured with a dead-weight gauge. The piston diameter is 0.17(in). What is the approximate mass in (lbm) of the weights required?

What will be an ideal response?


Pressure is force divided by area. So, the maximum force required (to be applied by the weights) is the maximum pressure to be measured times the area of the piston. The piston area is



The maximum pressure to be applied is For the standard acceleration of gravity to the piston. Thus, the mass of weights required is
