- An automobile weighing 1.19 x 104 N has weight equally distributed over its wheels. The weight of the car causes each tire to be slightly flattened on the bottom so that there is a surface area in contact with the road. The gauge pressure of the air in the tire is 1.90 x 105 Pa (27.55 lb/in2). Find the area of contact, assuming that the only forces on the section of tire in contact with the road are the air pressure and the normal force exerted by the surface of the road.What is the mass of air at 20 degree Celcius in a room with dimensions 3m by 4m by Sm? (P ar = 1.20 kg/m) Solution Relevant givens (check as many as possible): Sm 8m O 10m O 21 degree Celcius O 1.2 kg/m3What is the pressure 24.0 m below the surface of a lake? The pressure at the surface is 12.6 m H2O and the density of water is 1000 kg/m^3. Use the conversion factor 101 325 kPa = 10.33 m H2O.
- What is the density of water at 4oC and one atmospheric pressure?Air and oil with a temperature of 25 °C are flowing through a horizontal pipe with an inner diameter 1.5 in at a volumetric flow rate of Qc = 31 L/min and QL respectively. The pressure inside the pipe is kept at 44.1 psia. According to the Baker map, what = 0.34 L/min, is the flow pattern of this flow? Here, the density and viscosity of oil are p, = 860 kg/m° and 1.72 x 102 Pa - s, and the surface tension is o = 0.030 N/m.When a person inhales, air moves down the bronchus (windpipe) at 13.8 cm/s. The average flow speed of the air doubles through a constriction in the bronchus. Assuming incompressible flow, determine the pressure drop in the constriction. Neglect the change of pressure due to change in height ?y in the wind pipe. If the pressure goes down then the pressure drop is negative. Use 1.20 kg/m33 for the density of air.

Assume the temperature of mercury to be 10 degrees Celsius at which its density is 13570 kg/m3An automobile weighing 1.19 x 104 N has weight equally distributed over its wheels. The weight of the car causes each tire to be slightly flattened on the bottom so that there is a surface area in contact with the road. The gauge pressure of the air in the tire is 1.90 x 105 Pa (27.55 lb/in2). Find the area of contact, assuming that the only forces on the section of tire in contact with the road are the air pressure and the normal force exerted by the surface of the road. (The answer is not 0.06263 m2)A hall has a volume of 240 m3. An air-conditioning system is to replace the air in this hall every thirty minutes, using ducts that have a square cross-section. Assuming that air can be treated as an incompressible fluid, find the length of a side of the square if the air speed within the ducts is 6.0 m/s.

When the air volume of the container is reduced to 0.3 m³, the corresponding gauge pressure is (a) 54.22 kPa (b) 67.55 kPaV2. A plane cruising at an altitude of 5000 m (air temperature -17.5 C pressure 54.0299 kPa density 0.7361 kg/m3 ). If the dash speed dial shows 220 knot determine the hydrodynamic pressure reading of the Pitot tube in kPa including five significant figures. An air knot is 1.852 km/hr. Answer:A pressure gage connected to a tank reads 50 psi at a location where the barometric reading is 29.1 inHg. Determine the absolute pressure in the tank.
