Consider an airplane window (area 0.33 m2). If the
pressure inside the plane is atmospheric pressure and the pressure
outside is 21% of Patm, what is the force on
the window? Ignore the velocity of the airplane (i.e., ignore
Bernoulli's effect).

Consider the window (of area 0.34 m2) of an airplane. If the pressure inside the plane is atmospheric pressure, while the pressure outside is 24 % of Patm, find the magnitude of the force on the window. Ignore the velocity of the airplane (i.e., ignore Bernoulli’s effect).
Consider the window (of area 0.71 m2) of an airplane. If the pressure inside the plane is atmospheric pressure, while the pressure outside is 17 % of Patm, find the magnitude of the force on the window. Ignore the velocity of the airplane (i.e., ignore Bernoulli’s effect).
What is the net force on an airplane window of area 1000 cm2 if the pressure inside the cabin is 0.97 atm and the pressure outside is 0.85 atm? (Outward is defined as positive.)
The airspeed across the outside of an airplane window is 200 m/s . The cabin inside is pressurezed to one atmosphere, and assume that the density of air is 1.29 kg/m3 on both sides of the window. What is the pressure difference from inside to outside? What is the force on the window if the window size is 28 cm by 44 cm ?
At 30,000 feet above sea level, atmospheric pressure is only 224 torr. That’s why airplane cabins are pressurized. There isn’t enough air for you to breathe outside the plane! If we took a balloon filled to 3.86L at room temperature (21°C) and 0.947 atm, what would its volume be at 30,000 feet above sea level (outside the airplane!) if the temperature also reduced to -35.°C?
The pressure in the atmosphere is not constant, but fluctuates as the weather changes. If the pressure outside a window drops by 6% while the pressure inside does not change, what is the force on the window? Assume the area of the window is 2.3 m2. (The positive direction is toward the inside of the window. Indicate the direction with the sign of your answer. Assume that the initial pressure inside and outside the window is initially 1 atm.) N
At high altitudes the air pressure can drop quite noticeably. What is the net force on a 8.7x13 inch airplane window if at certain altitude the outside-cabin air pressure is Pout = 34 kPa and the inside-cabin pressure is supported at a level of Pin - 76.5 kPa? The net force on the window, Fnet - Units Select an answer If the same airplane window can withstand a twice as strong force as determined above, to what maximum value the...
The pressure in the atmosphere is not a constant but fluctuates as the weather changes. If the pressure outside a window drops by 10.1%, while the pressure inside does not change, what is the magnitude of the force on the window? Assume that the area of the window is 1.3 m2.
10. Air pressure inside a research submarine is 101,000 Pa. The total pressure outside the submarine is 201,940 Pa. What is the net force on a window with an area of 0.090 m´?
An airplane has an effective wing surface area of 21.9 m2 that is generating the lift force. In level flight the air speed over the top of the wings is 70.0 m/s, while the air speed beneath the wings is 47.0 m/s. What is the weight of the plane?
