Shown in fig. below, fluid A is oil (S.G. 0.82) and fluid B is salt solution (S.G. 1.10), z = 21.5 in, y = 7.0 in. The local acceleration of gravity and barometric pressure and both standard. Compute the pressure at point x if the specific gravities are relative to 62.4 lbm/ft water. %3D

As shown in Figure D, three water reservoirs are connected by three pipes. The diameters in each pipe is 1 ft and the Fanning friction factor in each pipe is 0.02. The effective lengths of each pipe are given in the Figure along with other relevant data. Determine the flow rate into or out of each reservoir as well as the Reynolds number in each pipe. (Hint: Start the computations by assuming that the water flows into reservoir B).

A Newtonian fluid with constant density flows in a parallel-plate apparatus that separated by a distance d and length L as shown in Figure 1. The top plate is moving in z-direction with a velocity uw. Derive the velocity distribution of the fluid, vz as a function of y using equation of motion in Appendix 1. List the postulates and you may neglect the gravity force.

fluid flow between parallel plates (Fig. 2) that are horizontal and a distance 2h apart. A constant pressure gradient is applied in the x-direction (dp/dx). The flow is fully developed laminar and steady.
