On A Given Day A Barometer On The Ground Floor

After riding the elevator to the 9th floor the barometer now reads 28 92 in.

On a given day a barometer on the ground floor. Suppose i use a barometer to measure the atmospheric pressure on the ground floor of a building. In the few weeks i ve had my barometer it s been between 30 00 and 30 30 the entire time usually only moving 05 1 in either direction on any given day. Assume the density of mercury ρ hg 13 600 kg m 3 and that the average. On a given day a barometer on the ground floor of the engineering sciences building reads.

Estimate the elevation change between the ground and 9th floors of the engineering sciences building. On the following sunny day mark the end of the shadow cast by the building at exactly that time. By the way i seem to remember from ground school at la guardia airport that the appropriate ratio is 1000 feet for each inch of mercury so if the precision of the barometer is the nearest 0 01 inch the precision usually given in weather reports you can expect 10 foot accuracy or about one floor. Note the exact time when the shadow reaches the other mark.

The main station is set on the ground floor one monitor is for upstairs and another one for outside. The color code makes it even nicer easy to tell the outdoors temp changes every 10 degrees. Repeat n times where n is a very large number. As ride the elevator up the atmospheric pressure decreases.

Now for the fun part. Using the barometer fingerprint map we can. The barometer will most likely bounce off the floor. On an aneroid barometer you ll have two hands.

After riding the elevator to the 9th floor the barometer now reads 28 92 in. Consider the case that the barometer reading at the top of the building is 751 mm hg and at the bottom of the building is 760 mm hg. Stand the barometer upright on the mark closer to the sun so the shadow will be approaching the other mark. The display is great very big and visible from across the room.

Keep in mind that changes will seem miniscule. Throw the barometer at the ceiling of the basement which is the floor of the building. Estimate the elevation change between the ground and 9th floors of the engineering sciences building. A barometer map with a reference point t b is generated and it is defined as map d 1 d 2 d 3 d n 1 t b where d i represents the barometer distance of floor i and i 1 n represents the floor number and b represents the barometer reading at the ground floor at timestamp t.

On a given day a barometer on the ground floor of the engineering sciences building reads 29 02 in.
