A bank of tubes is made of copper tubes. There are 20 rows of tubes in the flow direction set in staggered fashion with 15 cm longitudinal spacing and 10 cm transferred spacing. Each raw consist of 15 tubes, 1.5 m long. This bank is used to condense saturated steam at 120 °C, which passes through 2 ½ SCH 40 tubes. The steam heat transfer coefficient is 10000 W/m2.K. Water at 10 °C and 0.15 m/s is supplied to flow over the tubes in the bank to condense the steam. The tube surface temperature (Ts) is 118 °C and the water side has a fouling factor of 1.76E-4 m2.K/W. Calculate
please schematic and assumption
a) The rate of condensation in kg/s at which the saturated steam is condensed in this bank. (20 points)
- The pressure drop across the tube – bank by method 2. (20 points)
Hint: Assume Tm = 290 K. Check this assumption when you find Tm,o. and

P15) Methane gas at 20°C is to be preheated in a heat exchanger consisting of a staggered arrangement of 4-cm-OD tubes, 5 rows deep, with a longitudinal spacing of 6 cm and a transverse spacing of 8 cm (see Fig. 7.28). Subatmospheric pressure steam is condensing inside the tubes, maintaining the tube wall temperature at 50°C. Determine (a) the average heat transfer coefficient for the tube bank and (b) the pressure drop through the tube bank. The methane flow velocity...

Tube bank uses an aligned arrangement of 10-mmdiameter tubes with ST-Si-20 mm. There are 10 rows of tubes with 50 tubes in each row. Consider an application for which cold water flows through the tubes, maintaining the outer surface temperature at 27°C, while flue gases at 427°C and a velocity of 5 m/s are in cross flow over the tubes. The properties of the flue gas may be approximated as those of atmospheric air at 427°C. Using Zukauskas correlation determine...
