# With rise in temperature thermal conductivity of air Question 13

# In a reversible adiabatic process, the ratio of $$\frac{T_1}{T_2}$$ is equal to Question 14

# Chances of occurrenceof cavitation are high if the Question 15

# The general equation of continuity for three-dimensional flow of a incompressible fluid for steady flow is Question 16

# A liquid compressedin cylinder has a volume of 0.04 m$$^3$$ at 50 kg/cm$$^2$$ and a volume of 0.039 m$$^3$$ at 150 kg/cm$$^2$$. The bulk modulus of liquid is Question 17
