a. A single-phase transformer rated at 400/ 230 V at 10 kVA has 200 V placed across the primary winding, and a short circuit placed across the secondary winding. State whether, or not, the core of the transformer will saturate. A power company in Norway wishes to provide electricity to Sweden, via three-phase ac transmission. The equivalent transmission circuit for one phase is shown in Fig. 3. State how real power can be transmitted, while keeping the voltage at the receiving end (VR), at a desired level, without changing the line impedance (X), or the magnitude of the voltage at the sending end (Vs).

Andrew Foods, Inc., produces a sweet syrup made from corn syrup and beet syrup mixed with pure sugar. For each batch, 680 lbm of beet syrup (13% sugar, the remainder water) and 650 lbm of corn syrup (8.0% sugar, the remainder water) are mixed with pure sugar and 350 lbm of water is boiled off. Determine the amount of pure sugar that needs to be added to produce an 18% sugar content in the final product.
