density of air=1.225kg/m3
pressure=density*force of gravity*height of the air
height of the air=15-10=5m
pressure=1.225*9.8*5=60.025 pa
pressure=60.025/24=2.5 atm

You are assigned the design of a cylindrical, pressurized water tank for a future colony on Mars, where the acceleration due to gravity is 3.71 meters per second per second. The pressure at the surface of the water will be 105 kPa , and the depth of the water will be 14.1 m . The pressure of the air in the building outside the tank will be 88.0 kPa . Find the net downward force on the tank's flat bottom,...

A sample of hydrogen is collected over water at a temperature of 230C. The pressure inside the tube is determined to be 689 mmHg, and 12.10 mL of gas has been collected. What would the volume of collected hydrogen be at STP? a weird lab decided to use glycerin, a liquid with a density of 1.260 g/mL. If the water level inside the tube was 12.31 cm higher than outside the tube, and the atmospheric pressure measured 728 mmHg, what...

U-tube manometer are commonly used to measure pressure Po of the air space inside a water tank, see figure below. Given readings (measure from ground level) 20 = 200 cm, 21 = 90 cm, z2 = 120 cm, zz = 100 cm 24 = 110 cm. Determine the gauge pressure Po - Pa.

Water is to be delivered from a reservoir through a pipe to a lower level and discharged into the air, as shown in Fig. 7-23. For the data given in the figure, find the vertical distance between the point of water discharge and the water surface in the reservoir. Ans. 12.11 m 50-mm diameter pipe -0.00631 m 11.58 m Fig. 7-23 The pressure inside the pipe at S must not fall below 23.9 kPa absolute. Neglecting losses, how high above...

Problem2 (a) Suppose outside temperature is 55 °F while the temperature inside a building is 72 F. The building is heated but not air conditioned, so the partial pressure of water vapor is the same both inside and outside the building. Finally, suppose the dew point outside is 40°F What is the dew point inside? What are the relative humidities inside and outside the building? (We are most comfortable if relative humidity is between 30% and 50%-This question shows why...

Water flows with speed inside a long pipe and exits from the right into the air with a speed v 2 =9.2 m/s , as shown in the figure. The cross sectional area of the opening on the right is 7.0 cm ^ 2 while the rest of the pipe has a section of 14.0 cm ^ 2 . The vertical standing column of water has height h = 4.3m (not drawn to scale). What is the elevation meters from...
