It is good design practice to select a steam coil size so that:
a. 100% of the coil capacity is needed when the air temperature entering the coil is -1°C
b. At least 40% of the coil capacity is needed when the air temperature entering the coil is -1°C
c. At least 80% of the coil capacity is needed when the air temperature at the coil inlet is -1°C
d. At least 10% of the coil capacity is needed when the air temperature at the coil inlet is -5°C
e. It is twice the size that is required to handle the heating load
