Water flows at 0.1 m3 /s through the 100– mm–diameter nozzle and strikes the vane on the 150–kg cart, which is originally at rest. Determine the velocity of the cart 3 seconds after the jet strikes the vane. Start your analysis by first properly selecting your C. V. and then present the corresponding FBD. rhow = 1000 kg/m3 .

Consider a spherical container of inner radius , outer radius r2, and thermal conductivity k. express the boundary condition on the inner surface of the container for steady one-dimensional conduction for the following cases: (a) specified temperature of 50°c, (b) specified heat flux of 30 w/m2 toward the center, (c) convection to a medium at t with a heat transfer coefficient of h
