Avolume of sae 10w-40 oil at 40 °c (viscosity = 79.33 mpa·s) is fully contained between two identical long wide plates each having a surface area 9.0 cm2 and separated by a uniform gap between the plates (in the y-direction) of 500 µm. at time t=0, the top plate is moved forward (in the x-direction) at a velocity of 1.0 cm/s. for these conditions determine:
a) what is the velocity gradient dv_x/dy between the two plates? b) what is the stress on the bottom plate? c) what force is required to keep the top plate moving to the right? d) for a vertical, stationary, axis (perpendicular to both plates), what is the volumetric flow rate between the plates, and e) what is the average fluid velocity between the plates?

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
