Asmall wind tunnel in a university’s undergraduate fluid flow laboratory has a test section that is 15 by 11 inches in cross section and is 4.0 ft long. its maximum speed is 145 ft/s. some students wish to build a model 18-wheeler to study how aerodynamic drag is affected by rounding off the back of the trailer. a full-size (prototype) tractor-trailer rig is 52 ft long, 8.33 ft wide, and 12 ft high. both the air in the wind tunnel and the air flowing over the prototype are at 80 °f and atmospheric pressure. what is the largest scale model they can build to stay within the rule-of-thumb guidelines for blockage and what are the dimensions of the model truck in inches? the width of the model truck is in. the height of the model truck is in. the length of the model truck is i

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
