A boiler heats water flowing at the rate of 2,0 litres per minute from 27°C to 77°C. If the boiler operates on a gas burner, the rate of consumption of the fuel if its heat of combustion is `4.0xx10^4J//g` , is

A geyser heats water flowing at the rate of 3.0 litres per minute from 27C to 77C If the geyser operates on a gas burner,what is the rate of consumption of the fuel if its heat of combustion is 4.0*10^(4)J/g?]

A gaeyser heats water flowing at the rate of 3 kg per minute from 27^(@)C to 77^(@)C . If the geyser operates on a gas burner, what is the rate of consumption of fuel if the heat of combusion is 4 xx 10^(4) J//g? Given specific heat of water is 4.2 xx 10^(3) J//kg//K .

A geyser heats water flowing at the rate of 3.0 liter per minute from 27^(@)C to 77^(@)C . If the geyser operates on a gas burner and its heat of combustion is 4.0 xx 10^(4) J//g , then what is the rate of combustion of fuel (approx.)?

a geyser heats water flowing at the rate of 4 litrre per minute from 30^(@) "to" 85^(2) C . If the geyser operates on a gas burner then the amount of heat used per minute is

When 10 g of coal is burnt, it raises the temperature of 2 litres of water from 20^(@)C to 55^(@)C . Calculate the heat of combustion of fuel.

When water is heated from 0^@C to 20^@C its volume

Water at 0^@C was heated until it started to boil and then until it all changed to steam. The time required to heat water from 0^@C to 100^@C is 5 min and the time to change boiling water to steam is 28 minutes. If the flame supplied heat at a constant rate, the specific latent heat of vaporisation of water (neglecting heat losses, container etc. is (in J//g ). (specific heat of water s =4.2 J//g )
