👉 Device Measurement
Venturimeter rate of flow
Flow nozzle rate of flow
Orifice meter rate of flow
Bend meter rate of flow
Rotameter rate of flow
Pitot tube Velocity of flow
Hot wire anemometer Air & Gas velocity

👉Classification of Jump
Hydraulic Jump (HJ): Hydraulic jump is an example of steady rapidly varied flow(RVF)
Hydraulic jump occurs when a supercritical stream meets a Subcritical stream of sufficient depth.
👉Classification of jump
Type Initial Froude Number (F1) EL/E1 (%)
Undular Jump 1-1.7 0
Weak Jump 1.7-2.5 5 -18
Oscillating jump 2.5-4.5 18-45
Steady jump 4.5-9 45-70
Strong Choppy > 9.0 > 70
