The velocity of flow over a flat plate is doubled. assuming the flow remains laminar over the entire plate, what is the ratio of the new thermal boundary layer thickness to the original boundary layer thickness?

Given:

laminar flow

and since velocity of flow is doubled, we consider as new velocity and as original velocity

Explanation:

As per laminar flow, thickness, t is given by

t =

t =  

t =

where,

= Reynold's no.

therefore,

t ∝

Now,

=

=

therefore,

explanation:

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only
