1. If air within the tank is at an absolute pressure of 680 kPa and a temperature of 70C, determine the weight of the air inside the tank. The tank has an interior volume of 1.35 m (Hibbeler, 2015). 2. The bottle tank has a volume of 0.12 m and contains oxygen at an absolute pressure of 8 MPa and temperature of 20C. Plot the variation of the temperature in the tank (horizontal axis) versus the pressure for 20C T 80C. Report values in increments ofAT = 10C (Hibbeler, 2015). 1. The kinematic viscosity of kerosene is 9 = 2.39(10-6) . Determine its viscosity in FPS units. At the temperature considered, kerosene has a specific gravity of sgkerosene = 0.810 (Hibbeler, 2015). 2. If a force of P = 2 N causes the 30-mm-diameter shaft to slide along the lubricated bearing with a constant speed of 0.5 m/s, determine the viscosity of the lubricant and the constant speed of the shaft when P= 8 N. Assume the lubricant is a Newtonian fluid and the velocity profile between the shaft and the bearing is linear. The gap between the bearing and the shaft is 1 mm (Hibbeler, 2015). In 50 mm 0.5 m/s 1. Determine the distance that the column of mercury in the tube will be depressed when the tube is inserted into the mercury at a room temperature of 68F. Plot this relationship of h (vertical axis) versus Dfor 0.05 in. D 0.150 in. Give values for increments of AD = 0.025 in. Discuss this result (Hibbeler, 2015).
