AI Thread Summary
To determine the True Air Speed (TAS) from an Indicated Air Speed (IAS) of 200 knots at a pressure altitude of 25,000 feet, additional information is needed, particularly regarding the meaning of the "+1 knot" change in Vp. The forum participants clarify that IAS refers to indicated airspeed, while TAS is the true airspeed, which can differ due to altitude and temperature variations. The impact of being at 25,000 feet on IAS and its relationship to TAS is also questioned, highlighting the need for a more complete problem definition. Understanding these factors is crucial for accurately calculating TAS. Further clarification on the variables involved is necessary to proceed with the solution.

We probably need more info to be of any help. Can you define the problem more completely? What is meant by "Change in Vp is +1 knot."? I assume that IAS = indicated air speed, and TAS is true air speed?

What does being at 25000 feet elevation do to change IAS so it does not match TAS?

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}...
