I have a question for the effect and difference on a DC motor for the speed( rad/s) in time (sec) if you apply:
1. Nothing (so no charge in the circuit only the mecanic charge of the generator)
2. A resistant charge (only the resistant is plug in with the generator)
3. Short circuit (No exterior electric charge but the terminals are bounds together so an excessive amount of current flow into the circuit)
4. Capacitive charge (only the capacitor is plug in with the generator)
I would like to know a simple explaination of every result to know why it does that compared to the others please.

A steam Rankine cycle operates between the pressure limits of 1500 psia in the boiler and 1 psia in the condenser. The turbine inlet temperature is 800°F. The turbine isentropic efficiency is 90 percent, the pump losses are negligible, and the cycle is sized to produce 2500 kW of power. Calculate the mass flow rate through the boiler, the power produced by the turbine, the rate of heat supply in the boiler, and the thermal efficiency. Use steam tables

An ideal Otto cycle has a compression ratio of 7. At the beginning of the compression process, air is at 98 kPa, 30oC and 766 kJ/kg of heat is transferred to air during the constant-volume heat addition process. Determine (a) the pressure (p3) and temperature (T3) at the end of the heat addition process, (b) the net work output, (c) the thermal efficiency and (d) the mean effective pressure for the cycle. Use the IG model
