Stoichiometry - Engineering

Q1:

Pick out the wrong unit conversion of calorific value.

A 1 kcal/kg = 1.8 BTU/lb = 4.186 kJ/kg.

B 1 BTU/ft3 = 8.9 kcal/m3 = 0.038 MJ/m3.

C 1 BTU/lb = 2.3 kcal/kg.

D 1 kcal/m3 = 0.1124 BTU/ft3.

ANS:C - 1 BTU/lb = 2.3 kcal/kg.

The wrong unit conversion of calorific value is: "1 BTU/ft3 = 8.9 kcal/m3 = 0.038 MJ/m3." The correct conversion is: 1 BTU/ft3=8.9 kcal/m3=37.258 kJ/m31BTU/ft3=8.9kcal/m3=37.258kJ/m3 Therefore, the correct option is: "1 BTU/ft3 = 8.9 kcal/m3 = 37.258 kJ/m3."
