Application: Bimetal conductor. A conductor is made of two materials as shown in Figure 7.41. This is typical of bimetal devices. The device is connected to a voltage source.
(a) Calculate the current density in each material.
(b) Calculate the total power dissipated in each material.
(c) Assuming that each material has the same coefficient of expansion and the same power dissipating capability which way will the bimetal device bend? Explain.
Estimate the molar volume, enthalpy, and entropy for n-butane as a saturated vapor and as a saturated liquid at 370 K. The enthalpy and entropy are set equal to zero for the ideal-gas state at 101.33 kPa and 273.15 K. The vapor pressure of n-butan..
They use GF(p), with p = 54 and primitive element α = 2 User B makes cB = 123 public. If MA = 432 what will be the common key kAB that A and B use for their communication?
What tower diameter should be used for optimum conditions of minimum total cost per year?
Assume the amount of radioactivity is the same in each case. Explain your answer on the basis of the chemical properties of Sr and Xe. Why are the chemical properties of a radioactive substance important in assessing its potential health hazards?
Find the value of Ia for which the generator efficiency is a maximum.
Which of the transistor currents is always the largest? Which is always the smallest? Which two currents are relatively close in magnitude?
The unit is to operate 8000 h/year. Determine the height and diameter of the absorption tower at conditions of minimum annual cost.
Estimate the annual operating cost of providing refrigeration to a condenser with duty 1.2 MW operating at -5 ºC. The refrigeration cycle rejects heat to cooling water that is available at 40 ºC, and has an efficiency of 80% of the Carnot cycle ef..
Application: Spot welding of sheet stock. In an electric spot welding machine, the electrodes are circular with diameter d = 10 mm. Two sheets of steel are welded together (Figure 7.47). H the power density (in steel) required for welding is 108 W..
A 2300-V, three-phase, wye-connected, round rotor synchronous motor has a synchronous reactance of 3 Ω per phase and an armature resistance of 0.25 Ω per phase. The motor operates on load with a power angle of -15°, and the excitation is adjusted ..
The estimated cost of the pipes, per unit length is: schedule 40 carbon steel $5, schedule 80 carbon steel $8.30, stainless steel (304) schedule 40 $24.80. Installation and fittings for all the materials adds $16.5 per unit length. The downtime re..
If a mixture of steam and ethyl benzene is fed to an adiabatic reactor at 2 bar, 640 °C, estimate the equilibrium conversion and outlet temperature as a function of the ratio of steam to ethyl benzene. What ratio would you recommend using in pract..
