Froude number 0.
Leg length (L) was measured (m) from the anterior superior iliac spine to the medial malleolus in order to derive
Froude number (Fr) (Fr = [v.sup.2]/gxL: v = velocity, g = acceleration due to gravity, L =leg length) for each individual at each speed.
Notations A: Air vent area B: Radial gate width F:
Froude number g: Acceleration of gravity H: Water depth in the gate chamber [h.sub.0]: Full opening height of the gate [h.sub.1]: Water depth upstream of hydraulic jump [h.sub.2]: Water depth downstream of hydraulic jump [h.sub.g]: Time-dependent gate opening m: Constant n: Constant [Q.sub.a]: Air flow discharge in the air vent [Q.sub.w]: Water flow discharge at the gate [V.sub.1]: Mean flow velocity upstream of hydraulic jump [V.sub.a]: Mean air flow velocity in the air vent [V.sub.w]: Mean flow velocity under the gate [alpha]: Relative difference of gate discharge [beta]: Ratio of air flow to water flow discharge [lambda]: Dimensionless vent area [xi]: Dimensionless gate opening [eta]: Relative discharge error.
Accordingly, the
Froude number and Reynolds number are equal to 0.34 and 67857, correspondingly.
Ghodsian [3] studied hydraulic characteristics of sharp crested triangular and results showed that Di Marchi's coefficient for this weir depends upon
Froude number of main channel, apex angle, and weir height to upstream depth.

This suggests that the
Froude number or the effect of velocity is critical consideration in terms of accurately modeling jet breakup behavior.
For noninteracting pool fires in cross-flows, flame length has been shown to increase linearly with the
Froude number based on wind speed [22].
For liquid flow through a tube, a dimensionless parameter called the
Froude number (FR) is used by engineers to determine the liquid flow velocity necessary to expel the air from the high and low points of the tubing.
The Bond number represents the ratio between the surface tension and the gravity force, and the
Froude number represents the mean flow velocity relative to the velocity of the long wave.
Here, Heaven revealed a personal love of the
Froude number. But why is it important?
The form drag is a function of the
Froude number, ([C.sub.R](Fr)), defined as, equation (8):
