Question 4 Soalan 4] (a) A supersonic nozzle is attached to a constant diameter circular duct at its exit The duct diameter is the same as the nozzle exit diameter. Nozzle exit cross- section area is three times that of its throat. The gas (k1.4, R = 287 J/kg-K ) enters the nozzle with pressure and temperature of 10 bar and 600 K respectively with negligible velocity. If a normal shock occurs at a section in the diverging part of...

(a) A supersonic nozzle is attached to a constant diameter circular duct at its exit The duct diameter is the same as the nozzle exit diameter. Nozzle exit cross section area is three times that of its throat. The gas (k-14, R 287 Jg K) enters the nozzle with pressure and temperature of 10 bar and 600 Krespectively with negligible velocity. If a normal shock occurs at a section in the diverging part of the nozzle where the area ratio...
Problem 3 (20 points) A cross-flow heat exchanger consists of a bundle of 32 tubes in a long duct. Hot water at 150°C and a mean velocity of 0.5 m/s enters the tubes having inner and outer diameters...
Problem 3 (20 points) A cross-flow heat exchanger consists of a bundle of 32 tubes in a long duct. Hot water at 150°C and a mean velocity of 0.5 m/s enters the tubes having inner and outer diameters of 10.2mm and 12.5mm and has to be cooled to 136°C. The tubes are made of steel of thermal conductivity k-40 W/m.K. Air at 10°c enters the exchanger (unfinned) with a volumetric flow rate of 1.0 m3/s. The convective heat transfer coefficient...

just now i sent this questions.
this is the answer given. however the answer i afraid
that he used formula that is not for constant surface temperature
and noncircular formula.
this is the formula foe the noncircular tube. because
the question ask about triangle.
my problem is, i cannot answer question 1(b) that ask
the heat transfer coefficient, h. please help me. thank you.
this pic is a note on constant surface temperature.
