Homework Answers
yes in this case air flows through the house so obviously air flows in the window and out of the chimney and also since air flows over a chimney and hence pressure will be very low at the chimney when compared to window.

A strong wind blows over the house shown in the figure. The wind is much stronger over the house's roof than lower down, and the house has an open chimney. A window on the ground floor is open, and so are the doors inside the house. Which way will air flow through the house?

(3) As shown in the figure below, wind blows at a uniform, constant velocity of 60 mph over a six foot diameter, air- tight Quonset hut is located on a flat plain. Assume 2d, inviscid, irrotational flow and that the density of the air is 0.002 slug/ft? Voo a. Where on the surface of the hut should the vent A be located so that the pressure inside the hut is equal to P? b. Find the difference in static pressure...

A hurricane wind blows across a 8.00m×16.0m flat roof at a speed of 140 km/h . Part A: Is the air pressure above the roof higher or lower than the pressure inside the house? Pick one. Explain. The pressure above the roof is lower due to the lower velocity of the air. The pressure above the roof is lower due to the higher velocity of the air. The pressure above the roof is higher due to the lower velocity of...

A student with a third floor dormitory window 32 feet off the ground tosses a water balloon straight up in the air with an initial velocity of 16 feet per second. It turns out that the instantaneous velocity of the water balloon is given by the velocity function v(t) = -32t + 16, where v is measured in feet per second and t is measured in seconds. Let s(t) represent the height of the water balloon above the ground at time...

Young Jeffrey is bored, and decides to throw some things out of the window for fun. But since he is also very curious, he decides to do so in a controlled way. Jeffrey takes a rock, his tennis ball, and one of his father's golf balls and sets them on the sill of an open window. Then, he uses a flat board to carefully push them all out of the window at the same time. The second-story window is 14.0...

A student drops an object out the window of the top floor of a high-rise dormitory. (a) Neglecting air resistance, how fast is the object traveling when it strikes the ground at the end of 4.4 s? Express the speed in mi/h for a familiar comparison. mi/h Can things dropped from high places be dangerous to people below? (Assume that a falling object can be dangerous if its speed exceeds 35 mi/h.) Yes, an object dropped from a high place...
