Your boss tells you that water at 68 f is flowing in a cooling tower loop at a rate of 600 gpm, in an 8-inch inside diameter pipe. your boss asks you whether this flow is the laminar or turbulent flow regime. calculate the reynolds number and state whether the flow is laminar or turbulent.

Explanation:

The volumetric flow rate of water will be as follows.

       q =

         = 0.0378

    Diameter =

                   = 0.2032 m

Relation between area and diameter is as follows.

           A =

               =

               = 0.785 x 0.2032 x 0.2032

               = 0.0324

Also,     q = A × V

or,         V =

                =

                = 1.166 m/s

As, viscosity of water = 1 cP = Pa-s

Density of water = 1000

Therefore, we will calculate Reynolds number as follows.

 Reynolds number =

                                 =  

                                = 236931.2

Hence, the flow will be turbulent in nature.

Thus, we can conclude that the Reynolds number is 236931.2 and flow is turbulent.

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.

explanation:

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
