What is the Stagnation Pressure of a Body Moving Through Air?

AI Thread Summary
The discussion focuses on calculating the stagnation pressure of a body moving through air at 200 m/s, with upstream conditions of 100 kPa and 30°C. Two scenarios are considered: one accounting for compressibility and the other assuming incompressible flow, with the flow being isentropic. The stagnation pressure is crucial for understanding aerodynamic forces and energy conservation in fluid dynamics. Participants express confusion about the calculations and seek clarification on the concepts involved. Understanding these principles is essential for accurate analysis in aerodynamics.

A body moves through air at a velocity of 200 m/s. The pressure and temperature in
the air upstream of the body are 100 kPa and 30◦ C respectively. Find the pressure
at a point on the body where the velocity of the air relative to the body is zero (1)
accouting for compressibility and (2) assuming incompressible flow. Assume that the
flow is isentropic.


I have no clue! Please, help me! I'm in way over my head here.

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggle to understand the concept of the question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
