Suppose that you neglected to level the deadweight tester before doing the calibration, and the tester were 2.0 degrees off of plumb. Using weights intended to produce 100 psig, what pressure would the tester produce with this misalignment?

Pressure Instrument for Calibration Stops Reservoir Pressure Cylinder and Piston Valves Pump

Solution

Actual pressure = rho*g*h = 100

New height = h*cos2

New pressure = rho*g*h*cos2

= 100*cos2

= 99.939 psig
