What does v stand for in the formula of kinetic energy?
In the formula for kinetic energy, v stands for velocity. Kinetic energy is calculated as 1/2 multiplied by the mass of an object multiplied by the square of its velocity.
What is the formula for calculating the velocity of longitudinal waves?
The formula for calculating the velocity of longitudinal waves is v (E/), where v is the velocity of the wave, E is the elastic modulus of the material, and is the density of the material.
How do you calculate air nozzle velocity?
Air nozzle velocity can be calculated using the formula v = sqrt((2 * P) / ρ), where v is the velocity in meters per second, P is the pressure in pascals, and ρ is the air density in kilograms per cubic meter. Simply input the values of pressure and air density into the formula to determine the air nozzle velocity.
How fast does air with a velocity pressure of 0.20 in w.g. move through a round duct?
The velocity of air flowing through a round duct can be calculated using the formula: Velocity = (2 * velocity pressure) / (air density). Given the velocity pressure of 0.20 in w.g., the air density needs to be known to determine the velocity.
How fast does air with a velocity pressure of 0.20 in wg move through a square duct?
The velocity of air moving through a duct can be determined using the formula V = (2 * pressure / density)^0.5, where V is the velocity in ft/s, pressure is the velocity pressure in inches of water gauge, and density is the air density in lb/ft^3. Since no air density is provided, it's not possible to determine the exact velocity from the provided information.
