List the formulas of three soluble bromide salts and three insoluble bromide salts. Do the same exercise for sulfate salts, hydroxide salts, and phosphate salts (list three soluble salts and three insoluble salts). List the formulas for six insoluble Pb2 salts and one soluble Pb2 salt. What do you make of the formulas?
Discuss the consequent effects on the real and reactive power losses, and on the voltage drop across the series impedance of the transmission system.
Develop a mass balance for a continuous diafiltration step and indicate the volumetric flow rates and concentrations of different species in the different streams obtained.
A mixture of heptane/decane at 1.8 bar, 120 °C contains 80% by mol heptane. At what pressure should it be flashed to obtain a stream that is 90% rich in heptane? What are the composition of the liquid and the amounts of the two phases?
A Carnot cycle operating between 600 °C and 25 °C absorbs 1000 kJ of heat from the high-temperature reservoir. The work produced is used to power another Carnot cycle which transfers 1000 kJ of heat from 600 °C to a reservoir at higher temperature..
What is the magnitude of the signal, in volts, that you could expect from the microphone? Assume that we get a maximum signal when the flux varies from 0 to the value of Φ calculated in Part B. (Assume that sound has a frequency of order 500Hz.)Volta..
If the motor is operating on load with a power angle of -20°, and the excitation is adjusted so that the excitation voltage is equal in magnitude to the terminal voltage, determine the armature current and the power factor of the motor.
A 50-kW, 250-V, short-shunt compound generator has the following data: Ra = 0.06 Ω, RS = 0.04 Ω, and Rf = 125 Ω. Calculate the induced armature voltage at rated load and terminal voltage. Take 2 V as the total brush-contact drop.
What is fugacity? How does it relate the chemical properties of ideal gases to real gasses and what is the equation for it?
why a substance is being heated at a fast rate the temperature of decomposition will be the higher than the obtain at a
The system works reasonably well, all things considered, except that Old Fred has a heavy hand and on the average breaks 30% of the 120 eggs that pass by him each minute. At the same time, a check of the "X-large" stream reveals a flow rate of 70..
