A copper-nickel alloy of composition 50 wt% Ni-50 wt% Cu is slowly heated from a temperature of 1200°C (2190 °F).
(a) At what temperature does the first liquid phase form? (b) What is the composition of this liquid phase? (c) At what temperature does complete melting of the alloy occur? (d) What is the composition of the last solid remaining prior to complete melting?
Using a centrifugal pump, and a flow rate of 60 gal/min, calculate the break hp of the pump using water with a density of 62.4lbm/ft3 and do the same for a nonviscous liquid having a density of 0.85g/cm3.
why is the carnot cycle not suitable as an ideal cycle for all the power producing devices ?
A Pitot-static probe connected to a water manometer is used to measure the velocity of air. If the de?ection (thevertical distance between the ?uid levels in the two arms) is 7.3 cm, determine the air velocity. Take the density of air to be 1.25 k..
What would happen if the air filter was partially choked. If the piston rings were leaking state what you would expect the results of a, b, c, and d above would be.
Calculate the ultimate tensile strength (engineering) of a material whose strength coefficient is 700 MPa and a tensile test specimen which necks at an engineering tensile strain of 0.35.
A connection of rod of 50 mm diameter has a rectangular block 50 mm wide and 25mm thick forged at its end. A turned radius of 25 mm joins the rod and the block. Draw the projections of the rod showing curves of intersection.
Twenty-five samples of steel beam were chosen and tested for Young's Modulus. Eight had a modulus of E = 30 x 10^6 psi. Two had a modulus of E = 29 x 10^6 psi. Fifteen had a modulus of E = 30. x 1-^6 psi.
Determine the angle between his velocity vector and the line from his position to the airlock's position.
Use thin airfoil theory to show that the pressure coefficient across the length of the ellipse in the stream-wise direction is constant when it is assumed T
how long is required for half the ice cube to melt? State clearly all the assumptions you make in formulating your model of this problem.
engine B is supercharged with after cooling and has cylinder inlet condition of 80c and 130 k pa to avoid knock problem it is desirable to have the air-fuel temperature at the start of combustion in engine B to be the same as in engine A calculate..
