Answer:
(a)[tex]1.308\times 10^{-4}m/sec[/tex]
(b)57.33831 pound/cubic feet
(c)120.1095 hp
Explanation:
We have
(a) 760 miles / hour
We know that [tex]1\ mile\ =0.00062m[/tex]
And 1 hour = 60×60=3600 sec
So [tex]760miles/hour=\frac{760\times 0.00062meter}{3600sec}=1.308\times 10^{-4}m/sec[/tex]
(b) 927 kg/cubic meter to mass/cubic foot
We know that 1 kg = 2.20 pound
So 921 kg = 921×2.20=2026.2 pound
We know that 1 cubic meter = 35.31 cubic feet
So 57.33831 pound / cubic feet
(c) We have to convert to hp
[tex]5.37\times 10^3kj/min=\frac{5.37\times 1000kj}{60sec}=89.5kj/sec[/tex]
We know that 1 kj /sec = 1.341 hp
So 89.5 kj/sec = 89.5××1.341=120.1095 hp
