Exercise 4 A heat exchanger has 300 3/4-in BWG 16 tubes, 2 m length, arranged in two passes. It is used to heat up 58 kg/s of an oil whose properties are $\rho = 790 \text{ kg/m}^3 \text{ c} = 2,100 \text{ J/(kg} \cdot \text{ K) k} = 0.133 \text{ W/(m} \cdot \text{ K)}$ Viscosity as a Function of Temperature [kg/(m $\cdot$ s)] T ($^\circ$C) 57 67 77 147 177 $\mu$ [kg/(m $\cdot$ s)] $3.6 \times 10^{-3}$ $3.02 \times 10^{-3}$ $2.5 \times 10^{-3}$ $7.4 \times 10^{-4}$ $5.2 \times 10^{-4}$ The oil inlet temperature is $57^\circ\text{C}$, and the desired outlet temperature is $77^\circ\text{C}$. The heating medium is saturated steam at 927 kPa (condensation temperature = $177^\circ\text{C}$). Decide if the unit is appropriated for the service and, in that case, what fouling factor is allowed by the heat exchanger. Assume that the oil circulates into the tubes.
