Calculating Nozzle Flow Rate - Physics Forums Calculating Nozzle Flow Rate To work out the flow rate of water from a nozzle we need to work out the volume in a given period of time To do this we work out the area of the nozzle and then multiply it by the velocity of the water coming from the nozzle to give us volume per unit of time
Exit velocity of a gas through a hole - Physics Forums Question: How does the velocity of the escaping gas relate to the diameter of the hole? I am not sure even how to approach this My first impulse is to apply Bernoulli's principal as it basically states that there is a relationship between the pressure of a fluid and the velocity of a fluid
Air flow through a 90 degree bend - Physics Forums Fluid flows at different velocities within a pipe’s cross-section For well-developed, ideal flow, the fluid velocities will be highest near a pipe’s center, decreasing towards the pipe walls in symmetrical fashion In the case of a 90 degree elbow or similar union, the velocity profile is more complicated The attached photo is a typical velocity profile for a similar type of union The
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
Speed of falling object underwater - Physics Forums Is there any formula for underwater falling sphere which can measure the velocity of that sphere at any time before it reaches its terminal velocity? A sample question is: I dropped a sphere into water with 0m s initial velocity what will be the velocity of that sphere after 3s? {the radius and
Velocity of Fluid flow due to gravity - Physics Forums Energy conservation is sufficient to get a good estimate - if some mass m leaves the pipe at a height h below the water surface of the tank, its kinetic energy is m*h*g, this allows to find the velocity Finding the speed of the wheel is trickier if you do not want to waste huge amounts of water And you probably want some method to keep the height of the water in the tank constant
Solving for distance using only initial velocity and coefficient of . . . Actually, althought relating the Kinetic Energy equation to the equation about friction and distance might be conceptually valid, it isn't the clue this person needed At the early point (probably around chapter 4) of an "elementary physics" textbook, a student encounters problems where, given an initial velocity and coefficient of friction , the student is expected to provide the resulting
