correct me if i’m wrong i’m pretty sure it’s B i’ve had the same question
Given-
Power, P = 800W
Thickness, L = 0.6cm
Area, A = 160cm²
Thermal conductivity, k = 60W/mK
The heat conduction would be
Except 
all the values are 0.
Therefore,
Thus, the boundary conditions here would be
1. 
2. 
Answer:
The flow of a real fluid has <u>more</u> complexity as compared to an ideal fluid owing to the phenomena caused by existence of <u>viscosity</u>
Explanation:
For a ideal fluid we know that there is no viscosity of the fluid hence the boundary condition need's not to be satisfied and the flow occur's without any head loss due to viscous nature of the fluid. The friction of the pipe has no effect on the flow of an ideal fluid. But for a real fluid the viscosity of the fluid has a non zero value, the viscosity causes boundary layer effects, causes head loss and also frictional losses due to pipe friction hugely make the analysis of the flow complex. The losses in the energy of the flow becomes complex to calculate as frictional losses depend on the roughness of the pipe and Reynolds number of the flow thus increasing the complexity of the analysis of flow.

- Electric Motor
- Combustion Engine
