Carbon dioxide(co2)gas undergoes a process in a closed system fromt1=100°f,p1=20lbf/in.2tot2=400°r,p2=50lbf/in.2the entropy produced due to internal irreversibilities during the process is determined to be 0.15 btu/°r per lb of gas. the carbon dioxide can be modeled as an ideal gas. determine if the energy transfer by heat,q, is positive (into the system), negative (out of the system), or zero.

X=92.49 m

Explanation:

Given that

u= 21 m/s

h= 97 m

Time taken to cover vertical distance h

h= 1/2 g t²

By putting the values

97 = 1/2 x 10 x  t²          ( g = 10 m/s²)

t= 4.4 s

The horizontal distance

X= u .t

X= 21 x 4.4

X=92.49 m
