Question 40
XE-BNAT2 marksNeeds review
A fixed control volume has four one-dimensional boundary sections (1, 2, 3, and 4). For a steady flow inside the control volume, the flow properties at each section are tabulated below:
Boundary Section | Type | Density (kg/m ) | Surface Normal Velocity (m/s) | Cross-sectional Area (m ) | Specific Energy (J/kg) |
|---|---|---|---|---|---|
1 | Inlet | 1000 | 10 | 0.5 | 200 |
2 | Inlet | 1000 | 2 | 3.0 | 50 |
3 | Outlet | 1000 | 5 | 1.0 | 100 |
4 | Outlet | 1000 | 4 | 1.5 | 80 |
The rate of change of energy of the system which occupies the control volume at this instant is
J/s. The value of
