- Vertical circular motion minimum speed proof - Physics Forums
so the body reached the top let's take what happened so far, in reverse now the body has velocity of (rg)^0 5 to the other side, mg is still downward we KNOW the body will complete the half circle reversed motion, because we've just seen it complete it
- Finding Velocity given x and y velocities - Physics Forums
1 How do you find the velocity of an object if you are given the x and y components of the velocity? 2 Not sure! 3 It makes the most sense to use the Pythagorean Theorem to find the magnitude then trig to find the angle, but I've got a classmate telling me you simply add together the x and y components Which is it?
- Calculating Nozzle Flow Rate - Physics Forums
for measuring velocity of water so we have to calculate velocity using head calculation or from stagnation pressure which we measure using a pitot tube Calculate Velocity from Head We can use Bernoulli's Equation to calculate velocity of a fluid from head Head is the distance from outlet to top of water V= 2gh V = Velocity m sec or feet per sec
- Converting velocity to pressure - Physics Forums
Radiologists often use Doppler ultrasound to measure flow velocity change in a blood vessel with a stenosis- but I would like to make a conversion to a pressure differential Equation: P2-P1 = (V2^2 - V1^2) 2 (assuming frictionless system, blood density ~ 1 0 gm cm^3, and no change in height)
- Exit velocity of a gas through a hole - Physics Forums
The exit velocity is determined by the pressure difference between the tank and the environment and also the frictional forces both internal to the fluid and between the fluid and the orifice sides Ignoring frictional forces and assuming a constant pressure, the exit velocity of a fluid is always the same no matter how big the orifice diameter is
- Permeability of Metglas and Propagation Velocity - Physics Forums
The first is the velocity of wave propagation along the boundary between the material and air or space That will be close to the speed of light, slowed down by the dielectric constant of the surface coating The second is the velocity of propagation into the material, perpendicular to the surface, which is much slower
- Velocity of gases in a flue stack - Physics Forums
I know the flow rate of gas (products of combustion + air) entering a natural draught (no fans) flue If the flue is removing all the gas: velocity of flue gas = flow rate (corrected for thermal expansion) flue csa As the flue gas moves up the flue what happens to its velocity? In
- Velocity of Fluid flow due to gravity - Physics Forums
For our purposes, in this project we are assuming the height in the tank is constant, as you said This will ensure a constant pressure at the bottom of the tank, in theory keeping the flow of water constant I originally thought I could use the kinematic equations of physics to solve for the velocity after free falling a certain distance "h"
