Question:
A heating contractor must heat 0.2 kg/s of water from 15°C to 35°C using hot gases in cross flow over a thin-walled tube.
Your assignment is to develop a series of design graphs that can be used to demonstrate acceptable combinations of tube dimensions (D and L) and of hot gas conditions (Toc and V) that satisfy this requirement. In your analysis, consider the following parameter ranges: D = 20, 30, or 40 mm; L = 3, 4, or 6 m; T∞ = 250,375, or 500°C; and 20
Transcribed Image Text:
D= 20, 30, or 40 mm Hot gases T- 250 to 500C Tme = 35°C L= 3, 4, or 6 m Water n = 0.2 kg/s Tm= 15°C
