How do you calculate flow rate of a nozzle?
3 Flow rate
- Any nozzle will produce certain flow rate at a given pressure differential. …
- The flow rate for a given nozzle can be calculate by the following formula.
- Q= Flow rate.
- K = K factor for nozzle.
- P = Pressure differential at the nozzle.
- n = Is a constant that depends upon the spray pattern type.
What is pressure head in Bernoulli’s equation?
The “head” form of the Engineering Bernoulli Equation is obtained by dividing the energy form throughout by the magnitude of the acceleration due to gravity, g . for a pump, the head developed by a pump p h is always positive.
Which is Bernoulli’s equation?
Bernoulli's Principle—Bernoulli's Equation at Constant Depth P1+12ρv12=P2+12ρv22 P 1 + 1 2 ρ v 1 2 = P 2 + 1 2 ρ v 2 2 . Situations in which fluid flows at a constant depth are so important that this equation is often called Bernoulli's principle. It is Bernoulli's equation for fluids at constant depth.
What is Bernoulli’s equation in fluid mechanics?
Bernoulli's equation formula is a relation between pressure, kinetic energy, and gravitational potential energy of a fluid in a container. The formula for Bernoulli's principle is given as: p + 12 ρ v2 + ρgh =constant. Where, p is the pressure exerted by the fluid.
What is the formula of nozzle?
p/dg+ v^2/2g+ h= constant at any two sections. P is the pressure, d the density , & h the static height.
How do you calculate spray rate?
Divide the pounds per acre of active ingredient by its concentration in the product. If 3 pounds of active ingredient are needed per acre, and the product is an 80 percent powder, then divide 3 by 0.80 to get 3.75 pounds, the amount of powder needed per acre.
What are the 3 heads in Bernoulli principle?
The pressure head represents the flow energy of a column of fluid whose weight is equivalent to the pressure of the fluid. The sum of the elevation head, velocity head, and pressure head of a fluid is called the total head. Thus, Bernoulli's equation states that the total head of the fluid is constant.
