The velocity profile for the flow of a Newtonian fluid between two fixed, wide, parallel plates is given by the equation u => 1-0), where V is the average velocity. The fluid has a viscosity of 1 mPa. s. Also, V=0.35 cm/s and h= 5 cm. Determine: a. the shearing stress acting on the bottom wall b. the shearing stress acting on the plane parallel to the walls and passing through the centerline (mid-plane). Sketch the profile of the magnitude of the shear stress from the centerline to the walls. c. If the density of the fluid described in this problem is 1000 kg/m", is the flow laminar or turbulent?

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
