WEDGE CONE
• Use M‐β‐δ to find wave angle β. δ given by wedge
l
• Need M‐β‐σ relationship to find β
angle.
• Find M1n = M1sinβ• Use NS tables to find
• Use M‐β‐δ to findδ and M1n= M1sinβ and NS tables to find conditions at 2.Use NS tables to find
conditions at 2, which are same as at wedge.
• Need additional relations to find conditions at ‘c’
