1. A water jet with a flow rate of Q = 100 ft³/s is moving in the positive x-direction at 50 ft/s with a uniform velocity. The jet splits into two, with the upper and lower portions each diverted symmetrically by 45° as shown. The outflow velocity is uniform, and the speed is 20ft/s. All flows are steady. Note that $p = 1.94 slug/ft^3$, and the pressures are all atmospheric (hint – no pressure contributions...). a) Conservation of Mass: Assume that the jet is constrained to a depth of 1 ft. What is the jet height in the inflow and outflow sections, denoted by $h_1$ and $h_2$? b) Conservation of Momentum: Disregarding gravitational effects, what is the x-component of force required to hold the diverter in place? Please define the control-volume and show all steps in solving this problem.

Problem 5. Consider the continuous rolling mill depicted in the below figure. Suppose that the motion of the adjustable roller has a damping coefficient b, and that the force exerted the rolled material on the adjustable roller is proportional to the material's change in thickness: $F_s = c(T - x)$. Suppose further that the DC motor has a torque constant $K_t$, and a back-emf constant $K_e$, and that the rack-and-pinion has effective radius of R. (a) (2pt) What are the inputs and output to this system? (b) (3pt) Obtain the system equations by (i) dynamic analysis of adjustable roller and (ii) DC motor circuit analysis

An aluminum cylindrical fin ($k = 228 \frac{W}{m^oC}$), having a diameter of 1 cm and a length of 10 cm is attached to a surface having a temperature of $95^oC$. The fin is exposed to an ambient air at $20^oC$ and the heat transfer coefficient along the length and at the end is $8.51 \frac{W}{m^2 oC}$. Determine the temperature distribution and the heat flux a) neglecting heat transfer at the end b) accounting for heat transfer at the end.
