The nameplate on a 50-mva, 60-hz single-phase transformer indicates that it has a voltage rating of 78-kv: 86-kv. an open-circuit test is conducted from the low-voltage side, and the corresponding instrument readings are 8.0 kv, 39.6 a, and 86.2 kw. similarly, a short-circuit test from the low-voltage side gives readings of 4.53 kv, 321 a, and 77.5 kw. write a matlab script whose inputs are the rating (voltage and kva) and rated-load, unity-power-factor efficiency of a single-transformer and whose output is the transformer rating and rated-load, unity-power-factor efficiency when connected as an autotransformer.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
