Steam is condensing in a condenser at 100°C by a fluid which enter at...
Given data:
- Inlet temperature of fluid = 30°C
- Outlet temperature of fluid = unknown
- Steam temperature = 100°C
- NTU = 3.2
Calculation:
1. Determine the effectiveness of the heat exchanger using the NTU value:
\[ NTU = \frac{UA}{C_{min}} \]
2. Calculate the minimum heat capacity rate:
\[ C_{min} = min(m_{dot}C_{p}) \]
3. Use the equation for effectiveness:
\[ \varepsilon = 1 - e^{-NTU(1-\varepsilon)} \]
4. Calculate the outlet temperature of the fluid:
\[ T_{out} = T_{in} + \varepsilon(T_{steam} - T_{in}) \]
Therefore, by substituting the given values into the equations, we can calculate the exit temperature of the fluid used for condensing steam. The correct answer is option 'D' (97.13°C).
