Calculate the Reynold's number. As a rule of thumb, any Reynold's number < 2000 is considered laminar, 2000<Re<4000 is transitional, and above 4000 is considered turbulent.
Re = (velocity)*(diameter)*(density) / (viscosity)
velocity = 2 m/s
diameter = 3 inches (0.0762 m)
density = 1000 kg/m3
viscosity = 1x10-3 N*s/m2
Re = (2 m/s)*(0.0762 m)*(1000 kg/m3)/(1X10-3N*s/m2)
= 152,400
So,I would guess that you would have turbulent flow in this pipe.

What is external diameter?
The diameter is the measurement of a line that goes right through a circle, through the centre point. In cases where we have a ring or some other such object with multiple circles, we would have an external diameter and an internal diameter. The internal diameter is the diameter of the inner circle. The external diameter is the diameter of the outer circle.
What is the diameter in the US?
A diameter is the length of a chord passing through the center of a circle.
How are a chord and a diameter alike?
A diameter is a chord that passes through the circle's center.
What must the diameter go through of a circle?
through the middle
When blood flows in layers through the lumen of blood vessels in the middle of the lumen flowing fastest. This is know as what kind of flow?
Laminar flow.
What is critical velocity for 3 inch hose?
The critical velocity for a 3-inch hose depends on the fluid flowing through it. In general, critical velocity is the velocity at which the flow changes from laminar to turbulent. It can be calculated using the Reynolds number for the specific fluid and hose diameter.
How do you measure water flowing through 300mm diameter pipes?
Same as you would in inches 3.14159265 and PSI have to be known
What has the author E E O'Brien written?
E E. O'Brien has written: 'On the flux of heat through laminar wavy liquid layers' 'On the flux of heat through laminar thin films'
A 1.0 m length of metal wire is connected to a battery and a current of flows through it. What is the diameter of the wire The resistivity of the metal is?
To calculate the diameter of the wire, we would need to know the resistivity of the metal, the current flowing through the wire, and the potential difference across it. Without this information, we cannot determine the diameter solely based on the length of the wire.
What is the basic assumption inherent in Darcy's law?
The basic assumption inherent in Darcy's law is that the flow of fluid through a porous medium is proportional to the pressure gradient in the direction of flow. This assumes that the fluid is flowing through a homogeneous and isotropic medium.
What is the behavior of path lines of laminar flow?
Path lines in laminar flow are smooth, steady, and well-defined, with fluid particles following a predictable trajectory as they move through the flow field. The path lines do not intersect or cross each other in laminar flow, and the flow remains orderly and organized.
Where can someone purchase a Laminar flow hood?
Laminar flow hoods can be purchased from lab equipment suppliers, scientific supply companies, and online retailers specializing in laboratory equipment. It is important to ensure that the supplier offers high-quality products that meet your specific needs and requirements.

Which is encountered by the electrons while flowing through a conductor?
Usually resistance is encountered by electrons while flowing through a conductor.
On what factors the current flowing through a device depends?
Current flowing through a device depends on resistance offered by that device.
