Answer:
Explanation:C7H6O2 + (15/2) O2 = > 3H2O + 7CO2 delH = Σ stoichiometric coefficient* enthalpy of formation delH = (7*-393.509 kJ/mol) + (3*-285.83 kJ/mol) - (15/2 * 0) -(1*-385.2 kJ/mol) delH = -3226.853 kJ/mol benzoic acid ...
Answer:
friction factor is 0.01819
average speed v = 1.69 m/s
Reynolds number = 98786.7
and flow is turbulent
Explanation:
given data
diameter d = 0.052 m
roughness ε=0.0015 mm
length l = 200 m
ΔP = 100 kPa
to find out
friction factor f, Reynolds number Re and average speed v
solution
we solve this by hit and try assume flow is turbulent
so we can say pipe flow
...............1
here f is friction factor and l is length and d is diameter and ρ is density
so
f v² = 0.052 ................2
we know Reynolds number =
here u is viscosity of water that is 8.9 ×
Reynolds number =
put here v from equation 2
Reynolds number = ×
Reynolds number = .................3
we know that 1/√f is
f = 0.01819
friction factor is 0.01819
and from equation 2
f v² = 0.052
0.01819 v² = 0.052
average speed v = 1.69 m/s
and from equation 3
Reynolds number =
Reynolds number =
Reynolds number = 98786.7
so flow is turbulent
