How do you calculate hydraulic diameter?

39
The hydraulic diameter is calculated as 4 timesthe flow area divided by the wetted perimeter of theconduit.


In respect to this, how do you calculate the hydraulic radius of a pipe?

Hydraulic radius is the area of the water prismin a pipe or channel divided by the wetted perimeter. Thus,for a round conduit flowing full or half full, the hydraulicradius is d/4. Hydraulic radius measures the flowefficiency of a pipe.

Subsequently, question is, what is mean by hydraulic radius? Hydraulic radius is defined as the area of theflow section divided by the wetted perimeter, whereas, Hydraulicmean depth is defined as the area of the flow section dividedby the top water surface width.

In this manner, what is hydraulic diameter how is it defined what is it equal to for a circular pipe of diameter D?

Answer: Hydraulic diameter is defined asit is ratio of cross sectional area of the pipe to wettedperimeter of the pipe. This parameter useful to determinedthe Reynolds number for laminar or turbulent flow.

What is equivalent diameter in heat exchanger?

Shell side Equivalent (Hydraulic)Diameter. Equivalent diameter employed by Kern forcorrelating shell side heat transfer/flow is not a trueequivalent diameter. The direction of shell side flow ispartly along the tube length and partly at right angles to tubelength or heat exchanger axis.

How do you calculate the flow rate of a pipe?

If the liquid is flowing through a pipe, thearea is A = πr2, where r is the radius of thepipe. For a rectangle, the area is A = wh where w isthe width, and h is the height. The flow rate can bemeasured in meters cubed per second (m3/s), or in litersper second (L/s).

How do we find the perimeter of a circle?

Learn that the perimeter of a circle hasits own special name, called "circumference." The symbol isa capital C. It is calculated using the formula Pi x diameter, or3.14 x d = C. It can also be calculated by Pi x (2 x radius) = C or3.14 x (2 x r) = C.

What is wetted perimeter of a pipe?

The wetted perimeter is the perimeter ofthe cross sectional area that is "wet". The term wettedperimeter is common in civil engineering, environmentalengineering, hydrology, geomorphology, and heat transferapplications; it is associated with the hydraulic diameter orhydraulic radius.

What is characteristic length scale?

From Wikipedia, the free encyclopedia. In physics, acharacteristic length is an important dimension thatdefines the scale of a physical system. Often, such alength is used as an input to a formula in order to predictsome characteristics of the system.

What Reynolds number is turbulent?

While laminar flow is "orderly" turbulent flow is"Random" and "Chaotic". It is also found that a flow in a pipe islaminar if the Reynolds Number (based on diameter of thepipe) is less than 2100 and is turbulent if it is greaterthan 4000. Transitional Flow prevails between these twolimits.

How do you calculate Reynolds number?

The Reynolds number (Re) of a flowing fluid iscalculated by multiplying the fluid velocity by the internal pipediameter (to obtain the inertia force of the fluid) and thendividing the result by the kinematic viscosity (viscous force perunit length).

How do you calculate mean depth?

If you have several objects that have a depth,then you can calculate the average depth. Theaverage depth looks at how deep all the objects are whenconsidered together. The formula for average is thesum of all the depths divided by the number of depthsyou have. Measure all of your depths.

What is meant by hydraulic jump?

A hydraulic jump is a phenomenon in the scienceof hydraulics which is frequently observed in open channelflow such as rivers and spillways. When liquid at high velocitydischarges into a zone of lower velocity, a rather abrupt riseoccurs in the liquid surface.

What is meant by wetted perimeter?

In open channel flow, the wetted perimeter isdefined as the surface of the channel bottom and sides indirect contact with the aqueous body. Friction losses typicallyincrease with an increasing wetted perimeter, resulting in adecrease in heat.

What are the types of heat exchanger?

There are three main types of flows in a spiralheat exchanger: Counter-current Flow: Fluids flow inopposite directions. These are used for liquid-liquid, condensingand gas cooling applications. Spiral Flow/Cross Flow: One fluid isin spiral flow and the other in a cross flow.

What is a double pipe heat exchanger?

Double Pipe Heat Exchangers. In its simplestform, the double pipe heat exchanger, (also known as aconcentric pipe, hairpin, jacked pipe and jacketedU-tube heat exchangers), consists of a single tube mountedinside another. One fluid flows in the inner pipe, while asecond fluid flows in the outer pipe annuals.

Where are shell and tube heat exchangers used?

A shell and tube exchanger consists of a numberof tubes mounted inside a cylindrical shell. Figure 1illustrates a typical unit that may be found in a petrochemicalplant. Two fluids can exchange heat, one fluid flows overthe outside of the tubes while the second fluid flowsthrough the tubes.
