Question

An experiment is performed to determine the boiling characteristics of a special coating applied to the exposed surface. Under steady-state conditions, nucleate boiling is maintained in saturated water at atmospheric pressure, and values of T1 133.7C and T2 158.6C are recorded. If n 1, what value of the coefficient Cs, f is associated with the Rohsenow correlation

Answer 1

Answer:

hello your question incomplete attached below is the complete question and detailed solution

Answer : Csf = 0.0131

Explanation:

Attached below is the detailed solution

Given data :

ΔTe = 17.1⁰c calculated as ;Ts - Tsat = ( 117.1 - 100 )

Pe = 957.9 kg/m^3

Cp1e = 4217 j/kgk

Ue = 279 * 10^-6 n. s / m^2

Pre = 1.76

hfg = 2.257 * 10^6 J/kg

Pv = 0.5955 kg/m^3

б = 0.0589 N/m

q" = 664 * 10^3 w/m^2 ( calculated )

Input these values into equation 1 as contained in the detailed solution

Csf = 0.0131
