A 25-kVA, 2300:230-V, 60-Hz, single-phase transformer has the following parameters: resistance of high-voltage winding 1.5 Ω, resistance of low-voltage winding 0.015 Ω, leakage reactance of high-voltage winding 2.4 Ω, and leakage reactance of low-voltage winding 0.024 Ω. Compute the following:
(a) Equivalent series impedance referred to the high-voltage side.
(b) Equivalent series impedance referred to the low-voltage side.
(c) Terminal voltage on the high-voltage side when the transformer is delivering full load at 230 V and 0.866 power factor lagging.
Derive the ODE representing this system and solve for the concentration of the outlet stream as a function of time. Plot this until equilibrium is established - derive and solve the equation and plot the new temperature profile.
The rate constant of a chemical reaction decreases by decreasing the 1. pressure 2. concentration of reactants
For a reversible liquid phase reaction A-^R, the conversion is 33.3% after 8 minutes and equilibrium conversion is 66.7%. Find the rate equation for the reaction.
The mass transfer coefficients are HL=0.436 m and kGa=6.06x10-7kg mol/s m3Pa and are to be assumed constant in thetower for the given concentration range. Use equilibrium data from Appendix A.3. Bynumerical or graphical integration, determine NG. ..
