Mach Number A bluntnosed missile is flying at Mach2 at stand

Mach Number.

A blunt-nosed missile is flying at Mach2 at standard sea-level conditions. Calculate the temperature and pressure at the nose of the missile.

Solution

solution:

1)here as per steady flow energy equation for isentrophic flow,we get

ho=h+v^2/2

where at STP

To=298.15 K,Po=1 bar,k=1.4

2)hence temperature at missile tip is

T/To=[1+(k-1/2)M^2]^-1=.555*298.15=165.63 K

3)where pressure is given by

P/Po=[1+(k-1/2)M^2]^-(k/k-1)=.1278*1=.1278 bar
