What is the relationship between flow rate pressure?
With the increase in flow rate the velocity of the fluid increases. and with the increase in velocity the pressure decreases, because there will be pressure drop (Refer Bernoulli's Theorm). So with increase in Flow rate the pressure decreases.
Does warming a viscous fluid generally increase or decrease its flow rate?
Increase
Is the velocity of a fluid related to its temperature As in if a fluids velocity while moving a pipe increases does its temperature increase?
With any moving fluid, there will be a little bit of friction, which would increase temperature. But the heat could be dissipated to the surroundings just as fast as the friction is generating the heat, depending on the type of fluid, speed, and configuration of the pipe. For your question - the faster the flow, the more friction and therefore heat.
Why does the theoretical flow rate differ from the actual flow rate?
gravity,temperature type of fluid,pressure
When can you increase the flow rate of a fluid in your daily life?
The flow rate of a fliud or liquid could be increased (depending on the situation) by increasing the amount of the fluid, then channelising this fluid into a narrow channel.
What is a Dilatant fluid?
shear thickening viscosity and density increase during flow
Define bulk and mean film temperature?
bulk mean temperature is average temperature of the fluid through out its flow. film temperature is average of outer most layer of the fluid and the surface its flowing
Can control valves be used to increase the pressure of fluid in a flow line?
yes but not the volume
What is the difference between Restriction Orifice and Flow orifice or please explain the symbols RO Restriction orifice and FO Flow Orifice?
A restriction orifice (RO) is used to limit the flow through the pipe to a set flow by choking the flow at its sonic velocity. A flow orifice (FO) is usually used to determine the flow through the pipe from the pressure drop over the plate. There a normally two pressure taps (one on each side of the plate) and a pressure transmitter which determines the pressure drop over the plate. A formula is then used to convert this pressure drop to a flowrate for the specific fluid passing through the orifice. A FO usually has a temperature element to determine the gas temperature for use is the formula.
Does the flow that transfer heat within a fluid is called convection current?
Not unless the fluid is flowing due to temperature/density differences.
What is aconvection current?
A convection current is a natural flow or circulation of fluid due to a variation in its density due to temperature differences. As a fluid's temperature increases, its density reduces, and the fluid rises to be replaced by fluid at a lower temperature. Convection, together with conduction and radiation, is a method of heat transfer.
What is orifice meter?
Orifice meter is a flow measuring device used for calculating the pressure drop,flow rate and behaviour of the fluid moving through the pipe.
