The density of nitrogen contained in a tank is 1.5 kg/m 3 when the temperature is 26 ˚C. Determine the gage pressure of the gas if the atmospheric pressure is 97 kPa. Chapter 1, Problems, Question 1.36 A tire having a volume 2.5 ft 3 of contains air at a gage pressure of 30 psi and a temperature of 70 ˚F. Determine (a) the density of the air and (b) the weight of the air contained in the tire. Chapter 1, Problems, Question 1.41 One type of capillary-tube viscometer is shown in the figure: For this device the liquid to be tested is drawn into the tube to a level above the top etched line. The time is then obtained for the liquid to drain to the bottom etched line. The kinematic viscosity, ν , in m 2 /s is then obtained from the equation ν = KR 4 t where K is a constant, R is the radius of the capillary tube in mm, and t is the drain time in seconds. When glycerin at 20 ˚C is used as a calibration fluid in a particular viscometer the drain time is 1370 s. When a liquid
