A 24 in long bar with a cross sectional area of 1.0 in^2 is subjected to an axial tensile load of 10,000 lb. compute the stress, strain and the total elongation if the bar material is :
a) steel with E = 30,000,000 psi
b) aluminum with E = 10,000,000 psi
C) Titanuim with E = 16,500,000 psi
water flows in a long electrical heated tube with q constant . the velocity and temperature profiles are fully
a system of propane and n-butane exists in two phase vapor liquid equilibrium at 10 bar and 323 k. the mole fraction
In coal gasifiers, refractories and metals must withstand the coal/air or coal/oxygen combusting atmospheres. The Zr-Nb-Ti system is under consideration as alternative to the Fe and Ni alloy systems because the coal combustion degrades these alloy sy..
a refrigeration system is designed to operate between temperture limits of -10 c and 25 c. the power input to the steam
Air undergoes a poly tropic process in a piston-cylinder assembly from P1 = 1 atm, T1 = 70ºF to P2 = 3 atm. Employing the ideal gas model with constant specific heats at 80ºF, determine the work and heat transfer per unit mass, in Btu/lbm, if
What are the percentages of the total heat absorption taking place in the economizer, boiler drum and the superheater, respectively? Assume cp of air and water as 1.005 kJ/kg K and 4.2 kJ/kg K, respectively.
consider the flow of air over a vertical flat plate at a low velocity u1 in ambient pressure p1. the plate surface
a cylinder of cross-sectional area a is divided inot tow chambers 1 and 2 by means of a frictionless piston. the piston
A constant-area duct is fed by a converging-only nozzle. The nozzle receives air from a large chamber at p1=600 KPa and T1=550 K. The duct has a friction length of 5.3, and it is choked at the exit. What is the pressure at the end of the duct? If 80 ..
A Charpy V Notch test was conducted for an ASTM A572 grade 50 bridge steel. the average values of the test results at four different test temperatures were found to be
How long in time must the pressure pulse be to allow for a detonation to occur and what is the minimum distance that the shock must traverse to allow for a detonation to occur?
Calculate the change in velocity required in changing the position of a satellite in an orbit by 90 degrees. The initial and final orbit is circular around the Earth with a 15000 km radius. Calculate the delta velocity, semi-major axis and period for..
