1. Determine the approximate density of a Ti-6Al-4V titanium alloy that has a composition of 90 wt% Ti, 6 wt% Al, and 4 wt% V.
2. Calculate the unit cell edge length for an 80 wt% Ag-20 wt% Pd alloy. All of the palladium is in solid solution, the crystal structure for this alloy is FCC, and the room temperature density of Pd is 12.02 g/cm3.
3. Some hypothetical alloy is composed of 25 wt% of metal A and 75 wt% of metal B. If the densities of metals A and B are 6.17 and d vanadium are 8.57 and 6.10 g/cm3, respectively.
Kerosene at 20°C flows at 18 m3/h in a 5-cm-diameter pipe. If a 2-cm-diameter thin-plate orifice with corner taps is installed, what will the measured pressure drop be, in Pa?
How many engagement points on the flywheel would be necessary to make this machine safe? Show your work.
air at mass flow rate of 10 kgs at 1 atm 300 k point1 enters an adiabatic compressor and exists at 8 atm 600 k point 2.
warm air is contained in a piston-cylinder assembly oriented horizontal as shown in figure p.142. the air cools slowly
An air standard dual cycle operates with a compression ratio of 15. At the beginning of the compression the conditions are 17°C, 0.95 bar, and 3.8L. The amount of heat added is 6.3 kJ, of which one-third is added at constant volume and the remainder ..
A 3 liter vessel contains 2kg of water, 0.05kmol of steam, and 15cm^3 of ice (of density 990 kg/m^3). If the vessel is heated until its entire contents have vaporied, what is the density of the vapor?
