Q1 A circular cross-sectional pipe with length L = 2.5n meters and diameter D = 2n meters is filled halfway with water.
a) Calculate the resultant hydrostatic pressure force exerted by water on the pipe section A-B only.
D
b) Calculate the point of action of the force components.
Pwater = 1000n kg/m^3
n = (k + 1) where k is the last digit of your student number [For instance; if diameter is given as D = 100n cm or D = 100xn cm and the student number is 150A3039, then k = 9 and n = 9 + 1 = 10 and Dpipe = 10010 = 1000 cm]
