Two large plane surfaces are 2.8 cm apart. the space between the surfaces is filled with glycerine. what force is required to drag a very thin plate of surface area of 0.6 m^2 between the two large plane surfaces at a speed of 1.5 m/s, if (i) the thin plate is in the middle of the two plane surfaces, and (ii) the thin plate is at a distance of 0.7 cm from one of the plane surfaces? assume the kinematic viscosity ofglycerine is 1.19×10^-3 m^2/s

What precautions should you take to prevent injuries when dealing with heavy loads?

Carbon dioxide gas expands isotherm a turbine from 1 mpa, 500 k at 200 kpa. assuming the ideal gas model and neglecting the kinetic and potential energies, determine the change in entropy, heat transfer and work for each kilogram of co2.

Athin walled concentric tube exchanger is used to cool engine oil from 160°c to 60°c with water that is available at 25°c acting as a coolant. the oil and water flow rates are each at 2 kg/s, and the diameter of the inner tube is 0.5 m and the corresponding value of the overall heat transfer coefficient is 250 w/m2. oc. how long must the heat exchanger be to accomplish the desired cooling? cpwater=4.187 kj/kg-candcpengine el=2.035 kj/kg·°c, oil . 120]
