What is Dead-Weight Pressure Gage Calibration about?

1) A dead-weight pressure gage tester uses a piston and cylinder filled with oil to calibrate pressure gauges. Varying the mass on the piston creates different pressures in the oil. 2) The question asks to calculate the mass needed to create a pressure of 1.5x106 N/m2 assuming no leakage, the velocity profile of leaking oil in the gap, and the rate of descent and drag force on the piston from leaking oil. 3) The piston has a diameter of 10 mm and length of 70 mm, the oil viscosity is 0.5 kg/m-sec, and at
