On the floor of a high-rise building, atmospheric pressure is 750 mm. rt. Art., when on the ground it is equal to 757 mm. rt. Art. How high is this floor?
Given:
P1 = 750 millimeters of mercury = 99750 Pascal – pressure on a certain floor of the house;
P2 = 757 millimeters of mercury = 100681 Pascal – pressure at the earth’s surface;
c = 12/133 meter / Pascal – the coefficient of the dependence of pressure on height.
It is required to determine h (meter) – the height of the floor of the house.
h = (P2 – P1) * c = (100681 – 99750) * 12/133 = 931 * 12/133 = 11172/133 = 84 meters.
Answer: the floor of the house is located at a height of 84 meters.
