Figure P9-9a shows a compound epicyclic train. Shaft 1 is driven at 300 rpm CCW and gear A is fixed to ground. The tooth numbers are indicated in the figure. Determine the speed and direction of shaft 2.
calculate the corresponding pressure angle and radius R for points on the involute. Plot the series of points in polar coordinates and connect with a smooth curve to give the involute.
a feedwater heater extracts steam from a turbine at 600 kpa and 250degc which it combines with 0.3 kgs of liquid at 600
Determine the collision probability of the bromine molecules in Problem 1.- Find the temperature T at which Vmp = c (the velocity of light) for the neon atoms discussed in Examples 1 and 2.
A water cooled compressor changes the state of R-134a from a saturated vapor at 15 psia to a pressure of 120 psia. The fluid rate is 2.0 lbm/min, and the cooling water removes heat at a rate of 135 Btu/min. If the power input is 4.0 hp, determine the..
The disk has mass m, radius r and moment of inertia IG = mr2/2. The spring constant is k = mg/r. Find the velocity of the centre of the disc as a function of x
Since the change is transparent to the customer, the design engineer advises you to go ahead and use up any existing material of the model. How will MRP help you to deal with this issue?
Consider atmospheric air at 25°C and a velocity of 25 m/s flowing over both surfaces of a 1-m-long flat plate that is maintained at 125°C. Determine the rate of heat transfer per unit width from the plate for values of the critical Reynolds number..
1. What are the factors considered while selecting a boiler? 2. What are the various boiler mountings? 3. Define vacuum efficiency of condenser? 4. What is the effect of friction on the flow through a steam nozzle?

Determine the maximum in-plane stresses for a cylindrical tank made of steel (E = 205 GPa, ν = 0.30), having a mean radius of 2 m and a thickness of 20 mm, and subjected to an internal pressure p = 1 MPa.
Calculate the maximum bending stress σmax in the tie due to the loads P, assuming the distance L = 1500 mm and the overhang length a 500 mm.
Ten kilograms of water at 15° C and 700 kPa are contained in a cylinder as shown. Heat is transferred slowly causing the piston to rise. Determine the heat transfer and work done if the final condition is saturated vapor. Show the process on a T-v di..
