1. Molybdenum forms a substitutional solid solution with tungsten. Compute the number of molybdenum atoms per cubic centimeter for a molybdenum-tungsten alloy that contains 16.4 wt% Mo and 83.6 wt% W. The densities of pure molybdenum and tungsten are 10.22 and 19.30 g/cm3, respectively.
2. Niobium forms a substitutional solid solu- tion with vanadium. Compute the number of niobium atoms per cubic centimeter for a niobium-vanadium alloy that contains 24 wt% Nb and 76 wt% V. The densities of pure pure Ge and Si are 5.32 and 2.33 g/cm3, respectively.
3. Iron and vanadium both have the BCC crys- tal structure, and V forms a substitutional solid solution for concentrations up to ap- proximately 20 wt% V at room temperature. Compute the unit cell edge length for a 90 wt% Fe-10 wt% V alloy.

Fixed-price contracts, where the contractor bids a fixed price to complete a system development, may be used to move project risk from client to contractor.
Over time, dust accumulates on the refrigerator's con- denser coil, which is located behind the refrigerator, increasing the hot side resistance to Rh,d = 0.1 K/W. It is desired to have a refrigerator cooling rate of qin = 750 W. Using the results ..
A well-insulated tank in a vapor power plant operates at steady state. Water enters at inlet 1 at a rate of 125lb/s at 14.7lbf/in^2. Make up water to replenish steam losses from the plant enters at inlet 2 at a rate of 10 lb/s at 14.7 lbf/in^2 and 60..

Using MATLAB Simulink, set up the negative feedback system of and find the value of the gain
why is communication with the customer so important? explain the twin dangers of making many changes or not enough
A 4.40-ft^3 rigid tank contains saturated refrigerant-134a at 100 psia. Initially, 26 percent of the volume is occupied by liquid and the rest by vapor. A value at the top of the tank is now opened, and vapor is allowed to escape slowly from the tank..
