The armature terminal voltage is halved, with the field current and load torque remaining the same. (c) The field current and the armature terminal voltage are halved, with the horsepower output remaining the same.
Then find the voltage across the 50-Ω resistor and the total power supplied by the source
If the origin, o, is located at the wing tip and the leading & trailing edge curve is given above, find the constant c at the wing root and then calculate the chord of the wing at position 2 and position 3 as indicated in figure 1. (Marks Breakdow..
Additional data: Use the Lee-Kesler graphs for enthalpy and entropy. The saturation pressure of propane at -51.4 °C is 0.66 bar. Take the ideal-gas CP of propane at these conditions to be constant and equal to 67 J/mole K.
gold has a face centered cubic crystal structure where there are four atoms per unit cell.below is a calculated xrd
Use the total energy of charge distribution to calculate the total electrostatic energy of a uranium 235 nucleus. It has 92 protons and a radius of about 7.0 femtometers?
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..
A living plant contains approximately the same fraction of carbon- 14 as in atmospheric carbon dioxide. Assuming that the observed rate of decay of carbon-14 from a living plant is 13.6 counts per minute per gram of carbon
a. Develop a general equation that relates the average value of n to the mass of a given mixture of PCBs and the mass of AgCl produced. b. A 0.1947-g sample of a commercial PCB yielded 0.4791 g of AgCl. What is the average value of n for this samp..
Calculate equilibrium products at 500K for the reaction of 1 mole CO and 1 mole H2O according to the water-gas shift reaction (CO • H2O CO2 • H2) as a function of temperature four ways
Balanced wye-connected loads drawing 10 kW at 0.8 power factor lagging and 15 kW at 0.9 power factor leading are connected in parallel and supplied by a 60-Hz, 300-V, three-phase system.
in heat transfer terms , the surface temperature rises above the wet bulb surface ceases to behave as a wet surface - the surface temperature rises to dry bulb temperature and air as the moisture level fa..
