- Gauge pressure is the pressure read by a pressure gauge. The gauge pressure will be zero if the pressure is the same as the general atmospheric pressure, because the gauge measures only the excess above atmospheric pressure. The actual pressure will thus be atmospheric pressure plus gauge pressure. Atmospheric pressure is about 14 pounds per square inch. The Rankine temperature scale is the Fahrenheit verson of the absolute temperature, and absolute zero in Rankine is about -460 F. Now, imagine a football has been stored in a warm locker room at a temperature of 71 F, and has a gauge pressure of 12.5 pounds per square inch. Next, it is taken outside and cooled to 40 F. What will the gauge pressure be after this is done?In a hurricane, the mean sustained wind velocity v (in meters per second) can be modeled by v(p) = 6.31013-p, where p is the air pressure in millibars at the center of the hurricane. Estimate the air pressure, p, at the center of the hurrican when the mean sustained wind velocity, (v(p)), is 60 meters per second. Round to the nearest hundredth. mbar Blank 1:What are the air-standard assumptions?
