FIND THE PRESSURE EXERTED ON A 6FTX10FT WALL BY THE ATMOSPHERE, IF ATMOSPHERE PRESSURE IS 14.7 PSI.
To find the pressure exerted on a wall by the atmosphere, we need to use the formula:
Pressure = Force / Area
In this case, we need to calculate the pressure exerted on a 6ft x 10ft wall, given that the atmosphere pressure is 14.7 PSI.
Step 1: Convert the wall dimensions from feet to square inches.
Since 1 ft = 12 inches, we have:
Width = 6 ft x 12 inches/ft = 72 inches
Height = 10 ft x 12 inches/ft = 120 inches
Step 2: Calculate the area of the wall in square inches.
Area = Width x Height
Substituting the values, we get:
Area = 72 inches x 120 inches = 8,640 square inches
Step 3: Substitute the values into the formula:
Pressure = Force / Area
Pressure = 14.7 PSI / 8,640 square inches.
Therefore, the pressure exerted on the 6ftx10ft wall by the atmosphere is 0.0017 PSI (rounded to four decimal places).
