An acb sequence balanced three-phase y-connected source supplies power to a balanced, three-phase δ-connected load with an impedance of 9+15i ω/ϕ . the source voltage in the b-phase is 220 ∠−50∘v. the line impedance is 1 + 1i ω/ϕ. use the single phase equivalent circuit for the a-phase to find the current in the a-phase of the load.

On a average work day more than work place firs are reorted

A-mn has a cubic structure with a0 0.8931 nm and a density of 7.47 g/cm3. b-mn has a different cubic structure, with a0 0.6326 nm and a density of 7.26 g/cm3. the atomic weight of manganese is 54.938 g/mol and the atomic radius is 0.112 nm. determine the percent volume change that would occur if a-mn transforms to b-mn.

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
