The air velocity in the duct of a heating system is to be measured by a pitot-static probe inserted into the duct parallel to the flow. if the differential height between the water columns connected to the two outlets of the probe is 2.4 cm, determine

(a) the flow velocity and
(b) the pressure rise at the tip of the probe. the air temperature and pressure in the duct are 45°c and 98 kpa, respectively.

20.94 m/s, 235.44 Pa

Explanation:

Acceleration due to gravity g =

height h = 0.024 m

From density of air = P/RT

= (98000)/(287 * 318.14) =

Using Bernoulli equation

Here z1 = z2 (since the outlets have the same differential height) and  V2 = 0 (no velocity at the tip)

Solving and making V1 subject of the formula

= 20.94 m/s

Change in pressure P2 - P1= density of water * g * height

= 1000*9.81*0.024

=235.44 Pa

how is this a question? in order for me to answer it i have to understand the question

explanation:

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
