Show that for isothermal atmosphere e Z 71). (T is constant for isothermal atmosphere and p pRT). The pressure at the base of a skyscraper is 14.7 psia and at the top of the skyscraper is 14.4 psia. The temperature is constant at 70°F i.e. isothermal atmosphere. How tall is the skyscraper?
5-18E Hydrogen is contained in a piston-cylinder device at 14.7 psia and 15 ft'. At this state, a linear spring (F « x) with a spring constant of 15,000 lbf/ft is touching the piston but exerts no force on it. The cross-sectional area of the piston is 3 f?. Heat is transferred to the hydrogen, causing it to expand until its vol- ume doubles. Determine (a) the final pressure, (b) the total work done by the hydrogen, and (c) the...
The atmospheric pressure varies proportionally from sea level to height, and the air temperature drops by 6K for every T km increase (a) Draw a cylindrical volume that is height inside the atmosphere, and then calculate the pressure change and expression (dP/dy-pg) depending on the height. (b) obtain the temperature change of the atmosphere accordingto the height y(km) in the place where the sea level (y-0) is at ToK temperature. (c) obtain a barometric equation which allows for the change...

A J57 turbojet engine is tested at sea-level, static, standard-day conditions (Po = 14.696 psia, To =518.7°R, and Vo = 0). At one test point, the thrust is 10,200 lbf while the airflow is 164 Ibm/s and the fuel flow is 8520 lbm/h. Using these data, estimate the exit velocity Ve for the case of exit pressure equal to ambient pressure (Po - Pe).
If the air temperature is 73°F at sea level, what is the temperature at the top of Pike's Peak (elevation 14,000 ft)? (Hint: The temperature decreases rather uniformly in the troposphere.) _______ °F
A steam pipe is to transport 215 lbm/s of steam at 200 psia and 600°F. Calculate the minimum diameter this pipe can have so that the steam velocity does not exceed 59 ft/s. The specific volume of steam at the given pressure and temperature is 3.0586 ft/bm. The minimum diameter of the pipe is ft.
You wish to use a barometer to determine your elevation above sea-level. Local weather reports indicate that the temperature is 85°F and sea-level pressure is 30.25 inHg. If your barometer reads a pressure of 22.4 inHg, what is your elevation above sea level? Assume a temperature lapse-rate of m = 0.00357°F/ft, and a linear temperature-altitude relationship (T = T0 − mz).
The Earth's atmosphere at sea level and under normal conditions has a pressure of 1.01x10^5 Pa, which is due to the weight of the air above the ground pushing down on it. How much force due to this pressure is exerted on the roof of a building whose dimensions are 10.2 m long and 14.5 m wide?
