Terminated, mismatched line. The line in Figure 14.39 is given. The generator can be connected anywhere on the line. It is required that the generator be matched to the line so that there are no reflections into the generator. Find the closest location d to the load at which you can move the generator so that the generator is best matched to the line (that is, the reflection coefficient at the generator is minimum). Assume the phase constant on the line is known as β0.
A frictionless ramp connects A at (3m, 5m) to B at (12m, 17m). The ramp pushes a block with a force of 50N normal to the ramp surface. Express the force from the ramp as a vector *F (ignore the other forces that also act on the block holding it in..
What are the units of A - Write an expression for the rate of butane destruction, d[C4H10]/dt - What are the final pressure and temperature of the system when the system reaches steady state, in each case (dry air, air with H2O)?
The system acetone (1) and methanol(2) is well represented by the one parameter Margules equation using A = 0.605 at 50 degrees C. a) What is bubble pressure for an equimolar mixture at 30 C?
nitrogen gas is contained in a rigid 1-m tank initially at 10 bar 300k. heat transfer to the contents of the tank
Design a suitable vibration isolator, consisting of a mass, spring, and damper, as shown in Fig. 9.54(b), for the milling machine such that the maximum vertical displacement of the milling cutter, relative to the horizontal surface being machined,..
determine diameter of a circular rod of ductile material with a fatigue strength ,e=280 Mpa. Add a tensile yield strength of 350 Mpa. The member is subjected to a varying axial load from 700 kN to -300kN. Assume Kt=1.8 and factor of safety=2.
Schematically draw the evolution of the microstructure of Fe-C alloy as T decreases from 1000C to 500C, with the following composition (wt % of C)

It is required to produce an aluminum fraction that is 99% pure (by weight). Find the area and size of screen required.
Air enters the evaporator of an air conditioner at 14.7 psia, 90F, 200 ft3/min. R-134a at 20 psia, 30% quality enters at 4 lbm/min and leaves as saturated vapor at the same pressure. Find the exit temp of the air and the rate of heat transfer from t..
Assume the coefficient of friction between the mass and the horizontal surface as 0.25.
