A capillary tube viscometer is being selected to measure viscosity of a liquid food. The maximum viscosity to be measured will be 230 cP and the maximum flow rate that can be measured accurately is 0.015 kg/min. If the tube length is 10cm and a maximum pressure of 25 Pa can be measured, determine the tube diameter to be used. The density of the product is 1000 kg/m3.

An air receiver carries a pressure of 3500 kPa absolute @ a temperature of 25 C. A fire occurs near the receiver which causes the temperature to rise to 80 C. Neglecting the increased volume of the receiver due to expansion, calculate the air pressure at this temperature.

A cylinder of radius 0.17 m and height 0.71 m stands vertically and contains an oil with a density of 832.6 kg/m^3. The cylinder is sealed on one end by a moveable piston of mass 3.00 kg. An additional mass of 15.9 kg is placed on top of the moveable piston. Determine the resulting gauge pressure the oil in the bottom of the cylinder. Express your answer in PSI. (1 PSI = 6894.76 Pa)
