Question

& which term is not required to determine HCV using
Boy's colorlemeter?
@ Quan Hly of water
Initial Temperature
© Water equivalent
I final Temperature​

Answer 1

Solution:

(a) Quan Hly of water

Explanation:

• Boys gas calorimeter (gas calorimeter): An apparatus used to determine the calorific values of gaseous fuels based upon a counter flow heat exchanger in which water flowing in one direction is heated by burned gas flowing in the other.
• The basic formula for calculating HCV in Boy's calorimeter: In this $(t_{2} -t_{1} )$ is the rise in temperature of the water which is multiplied to its weight and divide by the volume of gas burned at standard conditions of temperature and pressure. Its unit is in Cal/m3.
• Initial temperature, final temperature and water equivalent use to determine HCV using Boys calorimeter.
• Hence, option a is the correct answer.
