1-50 A pressure gage connected to a tank reads 500 kPa at a location where the atmospheric pressure is 94 kPa. Determine the absolute pressure in the tank. Answer: Pabs = 594 kPa %3D

Consider a tall building. The air pressure at the bottom of the building is 101155Pa. The top of the building is 363m above. Assuming that the air density is constant at 1.225kg/m³, what is the percentage drop in pressure at the top of the building relative to the pressure at the bottom? Give your answer to 1 decimal place. Use the acceleration due to gravity of 9.81m/s².

At a certain point on the wing of the aircraft, the pressure is 37,803 Pa and the density is 45% of the standard sea level values. Determine the temperature (Kelvin) at that point? Use standard metric units and round off answer to the nearest hundredths.

1-53 The water in a tank is pressurized by air, and the pres- sure is measured by a multifluid manometer as shown in Fig. PI-53. Determine the gage pressure of air in the tank if h = 0.2 m, h, = 0.3 m, and h, = 0.46 m. Take the densities of water, oil, and mercury to be 1000 kg/m'. 850 kg/m, and 13.600 kg/m, respectively.
