How do you calculate velocity in a pipe?
To calculate velocity in a pipe, you can use the formula: velocity flow rate / cross-sectional area of the pipe. The flow rate is the volume of fluid passing through the pipe per unit time, and the cross-sectional area is the area of the pipe's opening. By dividing the flow rate by the cross-sectional area, you can determine the velocity of the fluid moving through the pipe.
How can determine the velocity of a wave?
To determine the velocity of a wave, you can use the formula: velocity = frequency × wavelength, where frequency is the number of waves passing a point in one second, and wavelength is the distance between two consecutive peaks of the wave. This formula helps calculate how fast the wave is propagating in a given medium.
Explain Why Nozzles are made convergent and Divergent?
According to Bernoulli's principle, pressure head, velocity head, and datum head are constant between two points. Additionally, continuity equation is area*volumetric flow rate is constant. So, in the convergent section, area is low which will result higher velocity and lower pressure. In the divergent section, area will increase, velocity will decrease, and consequently, pressure will increase.
What is area velocity method?
The area velocity method is a commonly used technique in open channel flow measurement. It involves measuring the velocity of flow at different points in the channel cross-section and integrating these velocities to determine the flow rate. By multiplying the flow rate by the cross-sectional area of the channel, the method can calculate the volume of fluid passing through the channel over time.
How does an orifice meter work to measure fluid flow rate?
An orifice meter works by measuring the pressure difference created when fluid flows through a small opening called an orifice plate. This pressure difference is used to calculate the flow rate of the fluid passing through the meter.

How do you calculate the flue gas velocity in airpreheater?
To calculate the flue gas velocity in an air preheater, you would need to know the volumetric flow rate of the flue gas passing through the preheater and the cross-sectional area of the preheater. You can then use the formula: Velocity = Volumetric flow rate / Cross-sectional area of preheater. This calculation will give you the velocity at which the flue gas is moving through the air preheater.

How do you calculate 25 bar steam condenstate pressure?
If the steam pressure is 25 bars the condensate pressure is at most 25 bars. Typically it is slightly less due to friction of the fluid passing through the steam traps. As the condensate approaches the condensate tank, where it is normally vented to atmosphere, the pressure decreases in the system to near atmospheric.
Is the passing score the composite score?
no ask your teacher it and she/ he will calculate it and tell you.

At what position does a pendulum bob reach its maximum velocity?
The pendulum bob reaches its maximum velocity at the bottom of its swing, when it is passing through the equilibrium position. At this point, all the potential energy has been converted into kinetic energy, resulting in the highest velocity.
What is the working principle of convergent-divergent nozzle?

Does a passing cold front increase or decrease air pressure?
A passing cold front typically decreases air pressure. Cold fronts move in and push warm air upward, creating lower pressure at the surface due to the rising air. This drop in pressure can lead to unsettled weather conditions.
