A stream of air at 12 bar and 900 K is mixed with another stream of air at 2 bar and 400 K with 2.5 times the mass flow rate. If this process were accomplished reversibly and adiabatically, what would be the temperature and pressure of the resulting air stream? Assume air to be an ideal gas for which Cp = (7/2)R.
A certain gas has a molecular weight of 30.0 a critical temperature of 310K. and a critical pressure of 4.5MPa. Calculate the density in kg/m3 of this gas at 465 K and 9.0MPa
In Number 1 it was assumed that the input and output flow rates could be independently varied. Consider a situation in which the outlet flow rate is a function of the height of liquid in the tank. Write the modelling equation for tank height assum..
You are presented with patient X who has a genetic disease. You discover a mutation inall aquaporin2 (AQP2) channels manufactured in the epithelial cells of the collecting ductso that there is no increase in water permeability when the mutated cha..
A mixture of ethanol and benzene is separated in a network of distillation and membrane separation steps. In one intermediate step, a near-azeotropic liquid mixture of 8,000 kg/h of 23 wt% ethanol in benzene is fed to a pervaporation membrane cons..
The uniform air gap is of length 1 mm, while the armature diameter is 0.5 m, and the axial length of the machine is 1.5 m. The field winding carries a current of 1 A (dc) and the rotor is driven at 3600 r/min.
Compute the mean torque if the stator current is 10 A (rms), the rotor is short-circuited, and the angle between the winding axes is 45°.
Consider the following information: i. The layer of dead skin on our bodies is sufficient to protect us from most -particle radiation.
Estimate a value for the total project cost that will give 98% confidence that the project can be carried out within the amount estimated.
Suppose that the adsorbate equation of state is given by z = 1 +ßn, where ß is a function of T only. Find the implied adsorption isotherm, and show under what conditions it reduces to the Langmuir isotherm.
Cost of installed unit, complete with distributor plates, supports, and all auxiliaries = 2.0 times purchased cost of shell and packing
A condenser is required to condense n-propanol vapour leaving the top of adistillation column. The n-propanol is essentially pure, and is a saturated vapourat a pressure of 2.1 bara. The condensate needs to be sub-cooled to 45ŽC.Design a horizonta..
A 30 mol% feed of benzene in toluene is to be distilled in a batch operation. A product having an average composition of 45 mol% benzene is to be produced. Calculate the amount of residue, assuming α = 2.5 and W0 = 100.
