The per-phase equivalent circuit shown in Figure 13.2.6 of a three-phase, 600-V, 60-Hz, four pole, wye-connected, wound-rotor induction motor has the following parameters: R1 = 0.75 Ω, R'2 = 0.80 Ω, Xl1 = X' l2 = 2.0 Ω, and Xm = 50 Ω. Neglect the core losses.
(a) Find the slip at which the maximum developed torque occurs.
(b) Calculate the value of the maximum torque developed.
(c) What is the range of speed for stable operation of the motor?
(d) Determine the starting torque.
(e) Compute the per-phase referred value of the additional resistance that must be inserted in the rotor circuit in order to obtain the maximum torque at starting.
Take the saturation temperature of n-propanol at 2.1 bar as 118oC. The otherphysical properties required can be found in the literature, or estimated.
Ethylene and propylene are valuable monomers. A key step in the recovery of these materials is fractionation of the olefin from the corresponding paraffin (ethane or propane). These fractionation steps require refrigeration of the overhead condens..

a)Draw and label the flowchart and carry out the degree-of-freedom analysis using balances on atomic species.(b)Determine the molar flow of oxygen supplied to the boiler.
Are small banks like Yolo Bank more or less likely to engage in off-balance sheet activities compared with large banks like BOA? Explain why or why not.How have banks managed to get around reserve requirements and regulation Q?
Calculate the oxygenated and deoxygenated hemoglobin levels given these parameters. Is this reasonable from a physiologic point of view? Explain.
Manometers connected across the venturi and the orifice contain a non-miscible liquid (sp gr = 1.56) in contact with the liquid mixture
For the design of internal-pressure cylindrical vessels, the API-ASME Code for Unified Pressure Vessels recommends the following equations for determining the minimum wall thickness when extreme operating pressures are not involved:
