Question
This is cryogenic subject question and i want ees code for the same as solution.
![(a) In a duct enlargement, the velocity reduces from 20 to 5 m/s.
(i) If it is a 20°-angle gradual enlargement, the pressure loss is given by
App = 0.45 ( pv, – Pv,)
Calculate the static regain.
(ii) What will be the static regain in an abrupt enlargement?
(b) A 10 cm diameter duct converges gradually to 7.5 cm diameter. The static
pressure and velocity just upstream of the reducer are 3 cm H,0 and 7.6 m/s
respectively. The dynamic loss coefficient of the reducer is 0.1.
Calculate:
(i) The flow rate.
(ii) The pressure loss in the reducer.
(iii) The pressure indicated by a U-tube water manometer connected to
pressure tappings at the upstream and downstream of the reducer.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8870759f-cc0f-4e65-b7dd-6b1c1330d65a%2Fbaf163ec-62c9-439b-90d8-3034486255ad%2Fujg2o37_processed.png&w=3840&q=75)
