It s stagnation pressure
What you need to do is to write Bernoulli equation between a far field point and a point on your hand.You will simply get the solution.It s not so complicated.What you need to know extra is the air density at 20°C.You can glance through appendixes of thermodynamics or...
here is the key
Start by writing Navier-stokes equations in cylindrical coordinates.And make reasonable assumptions to simplify the equations. Like, 1 The flow is steady and two dimensional in r-z plane. Here z is the coordinate pointing downwards.You can also chose it to be pointing upwards...
Hi to everyone.I were to solve a nonlinear equations system consisting of two unknown parameters and two equations.I have written a Matlab m-file to define the functions in order to solve them by embeded fsolve Matlab command.But I end up with an error occurring on the command window, when i...
