Any generator requires a given magnetic field to produce an emf. One way of obtaining the required magnetic field is a permanent magnet. In a car alternator there are no magnets but there is always a battery available. How do you suppose the alternator works? Note. An alternator is an ac generator.
She wishes to calculate a project's PW with estimated costs of $35,000 now and $7000 per year for 5 years beginning 1 year from now with increases of 10 % per year thereafter for the next 8 years. Use a real interest rate of 12% per year to make t..
What is the empirical formula of this compound and does this compound behave as an ideal gas
Calculate the fraction of water that is condensed from the air, the relative humidity of the air at 100°C, and the ratio m3 outlet air at 100°C/m3 feed air at 90°C.
Current transformer with air core. Calculate the induced voltage in an air-filled, uniformly wound toroidal coil of n turns and cross sectional area as shown in Figure 10.51. The central wire is very long and carries a current 1(t) = I0 sin ωt.
The equilibrium constant should vary with temperature according to the relation Kp = ae-b/T use the results of part (b) to determine the values of a and b by a graphical curve-fitting procedure. [Suggestion: Use the spreadsheet program from part (..
Design a sieve plate column to perform this separation, for a feed rate of 10,000 kg/hour. Treat the feed as a binary mixture of ethanol and water. Take the feed temperature as 20 °C. The column will operate at 1 atmosphere.
Propane gas at 22 bar and 423 K is throttled in a steady-state flow process to 1 bar. Estimate the entropy change of the propane caused by this process. In its final state, propane may be assumed to be an ideal gas.
In the manufacture of methyl ethyl ketone from butanol, the product is separated from unreacted butanol by distillation. The feed to the column consists of a mixture of 0.90 mol fraction MEK, 0.10 mol fraction 2-butanol, with a trace of trichloroe..
An irreversible Isomerizationreaction AR is carried out in a liquid phase in MFR. Thereaction is first order and the rate constant at 165oC is 0.7 hr-1.
Calculate the chemical potential of methanol in solution with acetic acid at xMeOH = 0.8, 80 °C, 0.4 bar. The reference state is the pure liquid at 80 °C, 0.4 bar. How is your answer affected by the fact that methanol is in the vapor phase at 80..
Use tabulated thermodynamic data to find ΔG° for this reaction at the standard temperature of 25°C. Then calculate the calculate ΔG°1000 for this process when it occurs at 1000 K.
