Question

Joules are Nm, which is kg middot m^2/s^2 Use this relationship and 1 Btu = 1.0551 kJ to determine what Btu using primary English units (ft, lb_m, degree F, sec, etc.)

Answer 1

`23851.35840\ lbft^2/s^2`

Step-by-step explanation:

`1\ Btu=1.0051\ kJ\\\Rightarrow 1\ Btu=1.0051* 1000 kgm^2/s^2`

The English units that are to be used here are pounds (lb) and feet (ft)

`1\ kg=2.20462\ lb`

`1\ m=3.28084\ ft`

`1005.1* 2.20462* 3.28084^2=23851.35840\ lbft^2/s^2`

The answer is
`1\ Btu=23851.35840\ lbft^2/s^2`
