To determine The velocity of water through the pipe. Explanation Given: The elevation between A and C ( h A C ) is 150 mm. The elevation between C and D ( h C D ) is 50 mm. The elevation between B and D ( h B D ) is 200 mm. The density of mercury ( ρ Hg ) is 13550 kg/m 3 . Calculation: The assumption made in the problem is given as follows: Consider that the point A and B is in same horizontal line so z A = z B = z . Draw the pipe with manometer as shown in Figure. Apply Bernoulli equation between A and B . p A ρ + V A 2 2 + g z A = p B ρ + V B 2 2 + g z B p A 1 , 000 kg/m 3 + V A 2 2 + 0 = p B 1 , 000 kg/m 3 + 0 + 0 p A 1 , 000 − p B 1 , 000 = − V A 2 2 p A − p B = − 500 V A 2 (I) Refer Figure and write the manometer Equation

(30 pts) Problem 1 A thin uniform rod of mass m and length 2r rests in a smooth hemispherical bowl of radius r. A moment M mgr 4 is applied to the rod. Assume that the bowl is fixed and its rim is in the horizontal plane. HINT: It will help you to find the length l of that portion of the rod that remains outside the bowl. M 2r a) How many degrees of freedom does this system have? b) Write an equation for the virtual work in terms of the angle 0 and the motion of the center of mass (TF) c) Derive an equation for the variation in the position of the center of mass (i.e., Sŕƒ) a. HINT: Use the center of the bowl as the coordinate system origin for the problem. d) In the case of no applied moment (i.e., M 0), derive an equation that can be used to solve for the equilibrium angle of the rod.
