2 The water in a 25-m-deep reservoir is kept inside by a 120-m-wide wall whose cross section is an equilateral triangle as shown in the figure. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Water 25 m 60 60 Determine the total force (hydrostatic + atmospheric) acting on the inner surface of the wall and its line of action. Take the value of g as 9.81 m/s2, the atmospheric pressure as 100,000 N/m2, and the density of water to be 1000 kg/m throughout. The total force (hydrostatic + atmospheric) acting on the inner surface of the wall is The distance of the pressure center from the free surface of water along the wall surface is X 108 N. m.
