Fluid Mechanics Problem 1) A rectangular gate 3 meters high and 1.2 meters wide is hinged at the top. A force to keep the gate closed is applied at the bottom with an angle of 45 degrees with the veritcal. Compute the following if the water surface is 0.9 meters below the top of the gate. Use 9.81kN/m^3 as water's specific weight. a. the total hydrostatic force acting on the gate in kN. b. the distance of the total hydrostatic force measured from the liquid surface in meter. c. the magnitude of the force at the bottom of the gate in kN. 2) Use 9.81kN/m^3 as water's specific weight. Consider the rectangular gate shown in the figure. If the gate has a length of 2 meters, determine: a. the force exerted by the water on the left side of the gate in kN. b. the force exerted by the water on the right side of the gate in kN. c. the horizontal force at B required to turn the gate about the hinge in kN.
