Saturated steam coming off the turbine of a steam power plant at 30 °C condenses on the outside of a 3-cm-outer-diameter, 35-m-long pipe at a rate of 45 kg/h. Determine the rate of heat transfer from the steam to the cooling water flowing through the pipe.

The answer 30.07J/sec

Explanation:

GIVEN DATA:

temperature of steam = 40 degree celcius

mass flow rate = 63 kg/h

from saturated water tables,

from temperature 40 °, enthalpy of evaporation value is 2406 kj/kg

rate of heat transfer (Q) can be determine by using following relation

putting all value to get Q value

Q = 45 *2406

Q = 108270 kJ/h

Q = 30.07 kJ/sec

i don't understand really? can u provide more information

u should make a machine that can make ice cream fresh!
