How do you calculate the passing velocity of pressure screens used in manufacturing of pulp and paper?
Basavarajhosamath
You convert the flow into m3/s and then divide that by the total area of the cylinder (m2) to give you the passing velocity in m/s. The key is finding the total area of the screen, which will depend on slot size, slot spacing, and cylinder type.

How do atoms pass their terminal velocity in a particle accelerator?
Passing the terminal velocity is clearly not possible, otherwise it could not be called the terminal velocity!
Why it is dangerous to stand near a railway line when a fast train is passing by?
Probably for the same reason you don't want to hang out next to a sinking ship or stand under a passing airplane - the air or water nearby is being pushed aside and creating a vortex. The air disturbance along with the ground vibrations may cause you to lose your balance and possibly fall into the passing train and maybe die. When a train is moving at a high speed; the velocity of air increases; according to bernoulli' s theorem, as the velocity increases, the pressure decreases. Thus the place where we are standing is a region of high pressure and the place where the train is moving is a region of low pressure. We are pulled from a region of high to a region of low pressure.
Which process conduction convection or radiation is used to remove heat from car raditor?
Its actually conduction - to the air passing through (due to the fan ... or the forward velocity of the car).
How do you calculate the relative speed of two trains passing each other?
If two trains are passing each other the relative speed can be found by adding the individual speeds of the two trains. This applies if the trains are passing each other in opposite directions. Should one be passing the other and both be moving in the same direction, the difference of the individual speeds would be the relative speed of the trains.
What is a skydivers velocity after 2 seconds?
Acceleration due to gravity is 9.8m/s/s, which is the same as 9.8m/s2. An acceleration of 9.8m/s/s means that with each passing second, the velocity of the skydiver increases by 9.8m/s. Therefore, after two seconds. a skydiver's velocity would be 19.6m/s. The acceleration will continue at 9.8m/s/s until the skydiver reaches terminal velocity, at which point the weight of the skydiver and the air resistance will be balanced, so the net force acting on the skydiver will be zero, at which point there will be no further acceleration.

The is the air passing over the evaporator has the greatest effect on the film factor?
Velocity
What is discharge in geography?
Discharge is the volume of water passing a given point over a set of time. To calculate discharge you do: Mean velocity x cross sectional area Steeper slopes should lead to higher velocities because of the influence of gravity. Discharge normally increases downstream, as does width, depth and velocity.
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.
Does a passing warm front increase or decrease air pressure?
it decreases
Does a passing cold front increase or decrease air pressure?
it decreases
What is the working principle of convergent-divergent nozzle?
A NOZZLE IS A DUCT WHICH CONVERT HEAT ENERGY INTO KINETIC ENERGY.IT INCREASES VELOCITY OF FLUID PASSING THROUGH IT ,AT THE EXPENCE OF PRESSURE. STEAM EXPANDS IN NOZZLE FOLLOW RANKINE CYCLE.FLOW THROUGH NOZZLE IS ISENTROPIC. mritunjay04@gmail.com
What would cause air pressure to rise?
Air pressure rises as you descend in altitude(more atmosphere above you pushing down), as the air is heated and expands in a fixed volume, as a high pressure region of air moves towards you, as the tangential velocity of air passing near you decreases(Bernoulli effect), as the elements that comprise the air become heavier or more energetic.
What percenege is passing?
To calculate the passing percentage, divide the number of students who passed by the total number of students in the group or class, then multiply by 100. This will give you the passing percentage.
How do you calculate current and voltage passing through light globes?
You can't "calculate" both. If you know the wattage & the line voltage then I = P / E and vice-versa.
