- Q1.B. Make a comparison between current control PWM rectifier in the abc reference frame and dq reference frame.arrow_forwardstep by steparrow_forwardThe power out of an adiabatic steam turbine is 5 MW and the steam enters turbine at 2 MPa and velocity of 50 m/s, specific enthalpy (h) of 3248 kJ/kg. The elevation of the inlet is 10 m higher than at the datum. The vapor mixture exits at 15 kPa and a velocity of 180 m/s, specific enthalpy (h) of 2361.01 kJ/kg. The elevation of the exit is 6 m higher than at the datum. Let g = 9.81 m/s². Assuming the ideal gas model and R = 0.462 KJ/(kg.K). The steam specific heat ratio is 1.283. Calculate:arrow_forward

For dry day, the temperature of outdoor is -10 °C and the inner room temperature is 20°C. Take the heat transfer coefficient on the inner and outer surface of the window to be h₁ = 10 W/m² °C and h₂ = 40 W/m² °C which includes the effects of insulation. Determine:arrow_forward
