A balanced delta-connected load has a per-phase impedance of 45 60° Ω. It is connected to a three-phase, 208-V, 60-Hz supply by a three phase feeder that has a per-phase impedance of 1.2 + j1.6 Ω.
(a) Determine the line-to-line voltage at the load terminals.
(b) If a delta-connected capacitor bank, with a per-phase reactance of 60 Ω, is connected in parallel with the load at its terminals, compute the resulting line-to-line voltage at the load terminals.
In Number 1 it was assumed that the input and output flow rates could be independently varied. Consider a situation in which the outlet flow rate is a function of the height of liquid in the tank. Write the modelling equation for tank height assum..
A small atomic bomb releases energy equivalent to the detonation of 20,000 tons of TNT; a ton of TNT releases 4x10^9 J of energy when exploded. Using 2x10^13 J/mol as the energy released by fission of 235U, approximately what mass of 235U undergoe..
