Two equal spur gears of 48 teeth mesh together with pitch radii of 96.0 mm and addendums of 4.00 mm. If the pressure angle is 20°, calculate the length of action Z and the contact ratio mp.
Determine the minimum necessary coefficient of static friction necessary so that the shims will remain in place.
For a combined turbine-generator efficiency of 83%, determine the net electric output. Disregard the effect of the KE correction factors.
Air at atmospheric pressure and a temperature of 25°C is in parallel flow at a velocity of 5 m/s over a 1m long flat plate that is heated with a uniform heat flux of 1250 W/m2. Assume the flow is fully turbulent over the length of the plate.
Determine an equation for the efficiency of the gear train in terms of the load (torque) on shaft 2 and determine the input power required at shaft 1.
a promising method of power generation involves collecting and storing solar energy in large artificial lakes a few
Write down an expression for uk, the general term of the sequence, and calculate the corresponding z transform when u(t) is
Air at 14.7 psia, 50oF, and 60% relative humidity is first heated to 72 o F in a heating section and then humidified by introducing water vapor. The air leaves the humidifying section at 75oF and 55% relative humidity.
It is proposed to build a one million kW electric power plant with steam as the working fluid. The condensers are to be cooled with river water at a flow rate of 5 x 108 lbm/hr. The maximum steam temperature will be 1000 F and the pressure in the con..
