What is the pressure on a horizontal surface with an area of \(2 m^{2}\) that is 4 m underwater?

Text Transcription:

2m^2

Solution 7E Step1 Given that Area = 2m 2 Height=4m Step2 To find The pressure on a horizontal surface Step3 We know that F(Force)= mass * acceleration = volume * density*g =Ahg Where is density of water, g is the acceleration due to gravity. Therefore, Pressure= Force A = Ahg=hg A By using 3 2 = 1000 kg/m ang g=9.8 m/s h=given Therefore, Pressure= 1000*9.8*4=39200 3 Hence , Pressure= 39200 N/m
