Water enters a fountain through a pipe with a cross-sectional area A₁ at a flowrate Q. The pressure in the inlet pipe is p₁. The water then leaves through a nozzle with a cross- sectional area A₂ and at an angle 0, as shown in Figure Q5. Both the inlet and the nozzle are at a height h₂, and the jet reaches a maximum height h3. You may assume that viscosity is negligible. a) Find the horizontal force on the block b) What is the horizontal-component (u₂), vertical component (v₂) and magnitude (V₂) of the velocity of the jet as it leaves the nozzle? c) What is the maximum height of the jet? You may assume that the horiztonal component of velocity is the same at every point in the jet. P₁ A₂. Ө h₂ h3 Figure Q5: Jet emitting from a fountain.

1. At time t = 0 a tank contains Qo Ib of salt dissolved in 100 gal of water. Assume that water containing 1/4 Ib of salt/gal is entering the tank at a rate of r gal/min, and that the well-stirred mixture is draining from the tank at the same rate. Set up the initial value problem that describes this flow process. Find the amount of salt Q(t) in the tank at any time, and also find the limiting amount QL that is present after a very long time. If r = 3 and Qo 2Q, find the time T after which the salt level is within 2% of Q. Also find the flow rate that is required if the value of T is not to exceed 45 min. %3D %3D
