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.
If the slip-ring voltage is 400 V, when the rotor frequency is 120 Hz, at what speed must the rotor be driven in order to give 150 Hz at the slip-ring terminals? What will the slip ring voltage be in this case?
In the reaction 2C8H18 + 25O2 --> 16CO2 + 18 H2O, the ratio of volumes of O2 to CO2
Natural gas composed of 60. mol% methane, 30. mol% ethane, and 10. mol% propane at 25 °C and 500. psia is fed at a rate of 50. m3/hr into a boiler. In the boiler it is blended with enough air to provide 20% excess oxygen and combusted.
How many possible plaintexts will the receiver find at the end of the decryption process?

A civil engineer is designing a road. At what angle should he bank the road surface in a curve of radius 70m so that there is no tendency for a vehicle traveling at 90 km/h to slip sideways, either up or down the banking.
An assembly line with 17 tasks is to be balanced. The longest task is 2.3 minutes, and the total time for all tasks is 18 minutes. The line will operate for 460 minutes per day.
Construct a reaction which has an induced kinetic differential equation that has solutions defined on the whole positive half-line of real numbers and which still does not belong to any of the reaction classes above.
The reactor initially contains one mole of ethanol and nothing else. The reaction is run at 550 °C and 2 bar until equilibrium is reached. What is the mole fraction of species at equilibrium?
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..
