It is required to produce an aqueous LiCl solution by mixing LiC1.2H20(s) with water. The mixing occurs both adiabatically and without change in temperature at 298.15 K (25°C). Determine the mole fraction of LiCl in the final solution
An elementary second order adiabatic reaction A+ B CD ? + is taking place in a CSTR. The feed to the reactor is equimolar A and B at concentrations of 2.4 mol/liter. The entering temperature is 300 K.
Calculate the temperature change when 10 mol of benzene is mixed with 40 mol of heptane adiabatically, 1 bar., if the initial temperature of the pure components is 20 °C. The heat capacity of the pure liquids are CP 1 = 134 J/mol, CP 2 = 222 J..
12. Comparing emitted Auger electrons (AES, Auger electron spectroscopy) with X-rays (EDX / EDS, energy-dispersive X-ray spectroscopy), what is the difference in the analysed sample volume (i.e. volume of the sample from which the signal comes)?
Calculate the mass of methane that must be burned to provide enough heat to convert 363.0 g of water at 43.0°C into steam at 117.0°C. (Assume that the H2O produced in the combustion reaction is steam rather than liquid water.)
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.
For the conditions indicated in Prob. 7, prepare a log-log plot of fluid velocity in feet per second versus optimum economic pipe diameter in inches. The plot should cover a fluid-velocity range of 1 to 100 ft/s and a pipe-diameter range of 1 to 1..
thermometry is the science of temperature measurement.nbsp for a thermometer to work we infer the temperature from the
A Carnot engine receives 250 kW of heat from a heat-source reservoir at 798.15 K (525°C) and rejects heat to a heat-sink reservoir at 323.15 K (50°C). What are the power developed and the heat rejected?
Determine the output voltage. Then indicate how the circuit may be modified to perform as a summer.
Calculate the tower height, Z, and tower diameter, D, needed so that the Z/D ratio is about 4 and at this optimum condition, what are the values of f, Tez, and air flow rate, G?
If the family of a patient in the intensive care unit submits the individual's living will document, should it be honored immediately or should there be a discussion between physicians and the family? Who should make the decision? Why?
Sinusoids of varying frequencies were applied to an open loop system and the following results were measured. (Data is from Seidel, 1975.) Construct a Bode diagram for the data.
