Question
![**Heating Process of Saturated Steam**
**Scenario:**
Saturated steam at 100°C is heated to 500.0°C.
**Objective:**
Use the steam tables to determine the required heat input (MW) if a continuous stream flowing at 250.0 kg/s undergoes the process at constant pressure.
**Calculations:**
1. **Formula:**
\[
Q = \dot{m} \cdot (h_2 - h_1)
\]
2. **Substitute the given values:**
\[
Q = 250.0 \, \text{kg/s} \times (3488 \, \text{kJ/kg} - 2676 \, \text{kJ/kg})
\]
3. **Calculate the energy:**
\[
Q = 203000 \, \text{kJ/s}
\]
4. **Convert to Joules per second:**
\[
Q = 2.03 \times 10^8 \, \text{J/s}
\]
5. **Convert to Megawatts (MW):**
\[
Q = 203 \, \text{MW} \, \checkmark
\]
---
**Additional Analysis:**
Use the steam tables to determine the required heat input (MJ) if 250.0 kg undergoes the process at constant volume.
**Formula:**
\[
Q = \, \text{___ MJ}
\]
(Where further details are required to complete this calculation using steam tables.)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc18c7a10-dc83-4a8d-a479-8de62488297a%2F22b81ffc-c48f-42aa-9305-d092b8952f47%2Fz7vyfqr_processed.png&w=3840&q=75)
