Explanation:
The given data is as follows.
Air is at and 14.6 psia.
= 0.00015 ft, Flow rate, (Q) = 48000
(a) Formula to calculate hydraulic radius is as follows.
=
= ft
Formula for equivalent diameter is as follows.
=
= ft
(b) Formula for velocity floe is as follows.
Q = VA
V =
= ft/min
= 24000 ft/min
(c) Formula to calculate Reynold's number is as follows.
=
= (as
and
= 0.0443 lb/ft. hr)
= 53742.66 hr/min
As 1 hr = 10 min. So,
= 3224559.6
(d) Formula to calculate pressure drop is as follows.
Putting the given values into the above formula as follows.
=
= 6.238
