A fluid at 1 bar and a temperature of 290 K enters a 3-cm-ID tube at a velocity of 0.5 m/s. The wall temperature is maintained at 372 K by condensing steam. What is the length of the pipe (in m) if we want to make the water temperature 343 K? The fluid property is given as below. All temperature unit (for the symbol 7) is Kelvin. p= 500-2(T298) kg/m³ Cp = 3 + 0.005 (T-298)² kJ/(kg K) T - 298 100 k = 550 + (mW/(m .K)) μ = 2 T-289 (mPa.s) A fluid at 1 bar and a temperature of 290 K enters a 3-cm-ID tube at a velocity of 0.5 m/s.
