Fluids Prelab 1 Gauge Pressure Ignoring air pressure, show that the pressure caused by a column of water 1.00 inches tall is 248.9 Pa. The difference in pressure between the top and the bottom of a column of fluid of height h is Δ P = ρg h The density of water is ρ water = 1000 kg m 3 Remember that 1 inch = 2 . 54 cm What is the difference in pressure Δ P ? 2 Atmospheric Pressure A smooth, thin, square piece of rubber, eight inches by eight inches, is sitting on a smooth table at sea level. What is the total force of the atmosphere on the material? Pressure is force per unit area, P = F A so the force F is 1

F = P A What is atmospheric pressure in units of pounds per square inch ( lbs / in 2 )? (Look in the inside cover of your textbook.) The length of one side of the piece of rubber is eight inches. What is the area of the piece of rubber in square inches? You should write the force in units of pounds . 3 The Weight of Air
