Consider the situation of Problem 10.67 at relatively high vapor velocities, with a fluid mass flow rate

Question:

Consider the situation of Problem 10.67 at relatively high vapor velocities, with a fluid mass flow rate of m = 2.5 kg/s.
(a) Determine the heat transfer coefficient and condensation rate per unit length of tube for a mass fraction of vapor of X = 0.2.
(b) Plot the heat transfer coefficient and the condensation rate for 0.1 ≤ X ≤ 0.3.


Data From Problem 10.67

Saturated steam at 1.5 bars condenses inside a horizontal,  75-mm-diameter pipe whose surface is maintained  at 100°C. Assuming low vapor velocities and  film condensation, estimate the heat transfer coefficient  and the condensation rate per unit length of the pipe.
