    What Is the G-Loading on an Aircraft During a Steady Pull-Up Maneuver?

    Homework Statement Consider an aircraft flying with speed 300 ft/s in a steady pull-up maneuver with pitch rate q = 0.1 rad/sec. What is the g-loading experienced by the pilot of the aircraft just as the maneuver begins (i.e. when the aircraft is still level)? The attempt at a solution So...

    Circulation of a stream function

    Homework Statement The stream function of a 2D incompressible flow is given by: \Psi=(\Gamma/2pi)*ln(r) Show that the circulation about a closed path about the origin is \Gamma and is independent of r. Homework Equations \Gamma=-\ointV dot ds The Attempt at a Solution So far I know that...

    Understanding Flow Field Continuity and Solving for f(r)

    Homework Statement A flow field is described by |V| = f(r) ; x^2 + y^2 = c (streamlines) What form must f(r) have if continuity is to be satisfied? Explain your results. Homework Equations equation of continuity: div V = d(ur)/dr + (ur)/r = 0 where (ur) is the radial...

    What is the Volume Flux of Fluid Through a Surface?

    would the normal vector be... n = cos(60) i + sin(60) j so then... dq/dS = V dot n = -cos(60) i + 2sin(60) j and... magnitude of dq/dS = sqrt( (-cos(60))^2 + (2sin(60))^2)

    What is the Volume Flux of Fluid Through a Surface?

    Homework Statement The velocity components of a flow are given by: u=-x v=y Compute the volume of fluid flowing per unit time per unit area through a small surface at (1,2) whose normal makes an angle of 60 deg with the positive x-axis. Homework Equations V= u i + y j (velocity vector)...
