Question
Dimensions of a swimming pool are 28.0 m by 9.5 m and its uniform depth is 1.8 m. The atmospheric pressure is 1.013 times 10^5 N/m^2. Determine the absolute pressure on the bottom of the swimming pool. Express your answer to two significant figures and include the appropriate units P_b = Value Units Calculate the total force on the bottom of the swimming pool. Express your answer to two significant figures and include the appropriate units F_b = Value Units What will be the pressure against the side of the pool near the bottom? Express your answer to two significant figures and include the appropriate units. P_s = Value UnitsExplanation / Answer
partA] Pbottom =Patm + Pwater where Pwater is rho*g*h
= 101300+ 1.8*1000*9.8
= 118940 Pa
in two sig fig, pressure = 1.2*10^5 Pa answer
partB] total force = pressure*area
= 118940 *28*9.5
= 3.2*10^7 N
partC] it will be same as bottom
= 1.2*10^5 Pa
