Q3/ A Porter governor has equal arms of 250 mm length each and pivoted on the axis of rotation. Each ball is of 50 N weight and the weight of the central load is 250 N. The radius of rotation of the ball is 150 mm when the governor begins to rise and 200 mm when the governor is at maximum speed. Find the range of speed, sleeve lift, when the friction at the sleeve is neglected.

A dry rock weighs 240 grams and has a bulk density of 2.4 grams per cubic centimeter. When saturated with pure water at room temperature (T=25°C), it weighs 250 grams. At room temperature, the specific volume of water is 1.00295 x10-3m3/kg. Calculate the porosity of the sample. (Permeability). A cylindrical core sample of 1 cm length and 1 cm2cross-section has upstream and downstream pressures of 2 atm and 1 atm, respectively, during steady state flow of water at 0.997 g/s at room temperature. Calculate the permeability of the core. Note: Water @ 25°C, viscosity = 1 cp, density of water = 0.997 g/cm3.
