WebFriction Loss in Fittings Valves As an aid, liquid sizing constants (Cv values) are shown for valves. These values are defined as the flow rate through the valve required to produce a pressure drop of 1 psi. To determine the pres-sure drop for a given GPM the following formula may be used. ∆P = (G2)(SG)/Cv2 where: AP = pressure drop G= Flow ... WebJan 11, 2024 · In the first few months, babies gain about 1 ounce (28 grams) a day. That slows at around 4 months to about 20 grams a day. As they turn 6 months old, many babies are gaining about 10 grams or less a day. Height.
