A continuous flow water heater (geyser) has an electrical power rating = 2 k W and efficiently of conversion of electrical power into heat = 80%. If water is flowing through the device at the rate of 100 cc/sec, and the inlet temperature is 10 °C, the outlet temperature will be

A 2100 W continuous flow geyser (instant geyser) has water inlet temperature = 10°C while the water flows out at the rate of 20 g/sec. The outlet temperature of water must be about

A 2100 W continuous flow geyser (instant geyser) has water inlet temperature = 10°C while the water flows out at the rate of 20 g/sec. The outlet temperature of water must be about

The two ends of a metal rod are maintained at temperatures 100^(@)Cand110^(@)C . The rate of flow in the rod is found to be 4.0 J/s. If the ends are maintained at temperatures 200^(@)Cand210^(@)C , the rate of heat flow will be :

A geyser heats water flowing at the rate of 4 litre per minute from 30^(@) "to" 85^(0) C . If the geyser operates on a gas burner then the amount of heat used per minute is
