????? what do u mean tier 2
Answer:
D.All of the above
Explanation:
Properties of hydrogen:
1.It is lighter than air.It has density about 0.089 g/L.
2.Hydrogen rapidly change from liquid state to gas,so special protection is required to protect it.
3.It is highly flammable gas.
4.Liquid form of hydrogen exits at -432 F .This is very low temperature so special protection requires to keep it in liquid form.
Answer:
buy a new one
Explanation:
go on newegg and you will most likely find one there
Answer:
15300 N
Explanation:
= Density of air at inlet
= Mass flow rate = 60 kg/s
= Inlet velocity = 225 m/s
= Density of gas at outlet = 
= Inlet area
= Outlet area = 
Since mass flow rate is the same in the inlet and outlet we have
Thrust is given by
The thrust generated is 15300 N.
