1. The problem statement, all variables and given/known data A cart has a tank of water on it which has a nozzle. Water jets out from the nozzle onto a turn vane oriented at theta = 30° which deflects the flow upward. The cart is held stationary by a rope as shown in the image below. Find the force in the rope if the velocity of the jet is 68.5 [ft/s] and the cross-sectional area is 0.8 [ft2]. 2. Relevant equations 3. The attempt at a solution I'm pretty confused about how to start this problem. I tried starting out with drawing a free body diagram (attached) and then found the mass flow rate: m=ρAv=(62.4lb/ft3)(0.8ft2)(68.5ft/s) m=3419.5 lb/s I was thinking somehow I could multiply that mass rate to get the weight of the tank or something, but now I'm thinking that wouldn't really make sense... Did I even need to find the mass flow rate? Then I summed the forces in the x and y direction: ΣFx=(FH2O)cos(30°)=T ∑Fy=FN+FA-Wtank-Wcart-(FH2O)sin(30°) +FB Is there someway I could calculate the pressure at the nozzle outlet? And then multiply that pressure by the area to get the force? Sorry if this seems a little scattered!
