A hydraulic shear applies 2000 lb force to a wedge. It is used to shear plate steel to rough size. The shear has a 1/4 inch thick cutting blade with a 45 degree slope. What is the ideal mechanical advantage of the wedge?
Water at 150C flows in 1½-inch Sch 40 steel pipe with a flow velocity of 2.86 m/s. The pipe expands to 4-inch Sch 40.
A. When the two torques are applied to the composite shaft, determine: the maximum shear stress magnitude in aluminium tube (1), the rotation angle of joint B and c.
What strategies could be used to counteract the increased Nitric oxides emissions with ethanol blended petrol?
Design a high pressure homogenizer for the manufacture of 10^6 kg per year of salad dressing.
A rigid bar of mass m and length L is released from rest in the horizontal position. What is the rod's angular velocity when it has rotated through 90°?
Longitudinal versus Transverse Vibrations in a bar, A 48 inch long by 2 inch diameter round steel rod (E=30e6 psi, density=0.28 lb/in3) is fixed at one end and free at the other. If the rod is struck transversely so that there is both a longitudin..
For a combined turbine-generator efficiency of 83%, determine the net electric output. Disregard the effect of the KE correction factors.
Determine the heat transfer coefficient for laminar flow over this cylinder. First, at your discretion, select an available set of experimentally obtained data from the literature. Then, this would provide you with a set of Reynolds numbers.
a) What is the temperature and state of the steam in the pipe? b) What is the quality of the steam in the pipe?
Ideal vapor-compression refrigeration cycle, An ideal vapor-compression refrigeration cycle, with ammonia as the working fluid, has an evaporator temperature of -20c and a condenser pressure of 12 bar
Consider a supersonic wind tunnel with test section Mach number of 2 and fixed geometry diffuser designed to operate with minimum stagnation pressure losses (smallest diffuser area).
The piston is then move in,and heat is rejected bt the air reversibly at constant pressure until the volume is the same as it was initially.Calculate the net heat flow and the overall change of entropy.sketch the process of p-V and T-s diagram.
