The formula to calculate the Duct Fitting Loss Coefficient (K) is:
\[ K = \frac{P_t}{P_d} \]
Where:
A duct fitting loss coefficient is a dimensionless number that quantifies the pressure loss in a duct system due to fittings such as elbows, tees, and transitions. These fittings cause turbulence and friction, which result in energy loss. The loss coefficient helps in designing efficient duct systems by allowing engineers to estimate the pressure drop across various fittings and thus ensure adequate airflow and system performance.
Let's assume the following values:
Using the formula to calculate the Duct Fitting Loss Coefficient (K):
\[ K = \frac{P_t}{P_d} = \frac{100}{50} = 2 \]
The Duct Fitting Loss Coefficient (K) is 2.
