स्थितियों का कौन सा संयोजन सही रूप से एक अस्थायी (unsteady), संपीड़ित (compressible), और गैर-समान (non-uniform) प्रवाह को दर्शाता है? (जहाँ ρ तरल घनत्व है, V वेग है, t समय है, और s स्थानिक निर्देशांक है)
- 1∂ρ/∂t = 0, ∂V/∂s = 0
- 2∂ρ/∂t ≠ 0, ∂V/∂s ≠ 0✓
- 3∂ρ/∂s = 0, ∂V/∂s = 0
- 4∂ρ/∂t = 0, ∂V/∂s ≠ 0
सही उत्तर देखें
∂ρ/∂t ≠ 0, ∂V/∂s ≠ 0
