6.4.5 Pressure Drop
6.4.5.1 Pressure Drop and Correction Factors
The pressure drop with 20 °C (68 °F) water was calculated with a 13 mm (0.5 in) pipe of 1 m (3.3 ft) length at inlet and outlet.
The pressure drop with 48 °C (118 °F) antifreeze can be calculated with the help of the graphs by multiplying them by correction factors.
