The streamlines in a certain incompressible, two-dimensional flow field are all concentric circles so that vr=0. Determine the string function for 1) V(theta)=Ar and for 2) V(theta)= Ar^(-1) where A is a constant in both cases. Use cylindrical coordinates to define the Stream Line function
An adiabatic turbine has steam flowing steadily through it. The inlet conditions of the steam are P1=6 MPa, T1= 400C and v1=80 m/s, while the exit conditions are P2= 40kPa, .9 quality x=.9, and v0= 50 m/s. The mass flow rate of the steam is m= 20kg/s..
