The power transferred across the air gap of a two pole induction motor is 24 kW. If the electromagnetic power developed is 22 kW, find the slip. Calculate the output torque if the rotational loss at this slip is 400 W.
For a feed rate 2000 kg/h of solution, composition 30% w/w MEK, determine the number of stages required to recover 95% of the dissolved MEK, using 700 kg/h TCE, with countercurrent flow. Tie-line data for the system MEK-water-TCE percentages w/w, ..
Would this method be acceptable for income-tax purposes if the income-tax laws do not permit annual depreciation rates greater than twice the minimum annual rate with the straight-line method?
A solution of the two components that contains 62% mol toluene is slowly heated at constant pressure. When the solution begins to boil the temperature reads 120 °C. What is the pressure?
Determine the percentage reduction in the applied voltage (i.e., the percentage tap on the autotransformer).
What is the speed of the rotor field at full load (i) with respect to the rotor? and (ii) with respect to the stator?
List out the different biological process involving acids and bases with relevant equations and in adverse conditions how is the pH level maintained in biological systems?
A particle with the mass of a proton is trapped in a box. The particle falls from the state to the state and emits 0.16 meV of energy. What is the size of the box? (nm
If the excitation is adjusted such that the magnitudes of the excitation voltage and the terminal voltage are equal, and if the motor is taking 20 A, find the torque developed.
Calculate the tap pings k on a three-phase autotransformer to limit the starting current to 4 times the full load current. For such a limitation, determine the ratio of starting torque to full-load torque.
Consider a diatomic gas, N2, at 298 K. This gas is compressed reversibly and adiabatically from 15 dm3 to 5.0 dm3. Assume that the heat capacity of this gas is CV=5R/2, and that it behaves ideally. Calculate the final temperature, T2, of the gas.
a. How many design variables must be specified in order to calculate the output stream compositions and flow rates? b. How would you optimize these variables if the objective of the separator was to maximize recovery of condensable components into ..
