Q3. (a) Determine the resulting hydrostatic force of water acting on the cylindrical wall of the tank and the angle of this force direction vs. horizontal, if R = 0.2m, the wall is b = 0.3 m wide into the paper, and the height of the water level in the narrow 3 mm diameter tube is h = 0.4m. Use the following inputs: p = 1000 kg-m³ and g = 9.8 m-s? R (b) The remotely navigated drone-submarine mysteriously managed to get into the above reservoir, but it seems it being trapped. Moreover, it is something wrong with submarine plunging mechanism: it cannot move in the vertical direction. Soon the oxygen required to supply some equipment of this tiny but expensive submarine will be over. Remote operator 1 suggests the following: "Well, let's make the 5mm sharp orifice by torpedoing the wall, and then. let me use the equation for the H=0.8m orifice velocity as V = Ca /2gH to calculate the time for emptying the tank." Operator 2 objects saying: “No, it will be correct if using V = Ca/2g(h +H)." %3D a sharp edge round orifice submarine! Assess the proposals of operators 1 and 2 (2 – 4 sentences, no more!). Note: you don't need to carry out any calculations here.
