TRANSFORMERS Find the all-day efficiency of a transformer having maximum efficiency of 98.5 per cent at 20 KVA at unity power factor and loaded as follows 11 hours: 5 kW at 0 7 power factor lagging 6 hours: 8 kW at 0.8 power factor lagging 7 hours: no load The maximum efficiency of the transformer occurs at 80 per cent of full load.​

Fluids at rest possess no flow energy. a)- true b)- false

Afour cylinder four-stroke in-line engine has a stroke of 160mm, connecting rod length of 150mm, a reciprocating mass of 3kg and its firing order is 1-3-4-2. the spacing between cylinders is 100mm. i. show that the engine is in balance with regard to the primary inertia forces and primary 3. a and secondary inertia couples. li determine the out of balance secondary inertia force ii. propose ways of balancing this out of balance force and discuss the challenges that will arise
