To produce peak power, Gavin burns $18\mathrm{.}5$ short tons of coal per minute. How many

kilograms of coal does Gavin burn per minute $($kg$/$min$)?$ Per day $($kg$/$day$)?$

$4.$ If the coal has an energy content of $12,700$ BTU$/$lbm$.$ What is the energy of the coal in kJ$/$kg$?$

$5.$ A home uses $2\mathrm{.}05$ cubic feet of natural gas in a day. How many cubic meters of natural gas

were consumed per month assuming $30$ days in that month?

$6.$ If the natural gas from Problem #$5$ has an energy content of $1025$ BTU$/$ft $3,$ determine the

energy content of the natural gas in kJ$/$m $3$

$7.$ Using the information from Problems #$5$ and #$6,$ how much energy in BTU and kJ were

consumed by that home from natural gas last month?

$8.$ A F$-150$ Lightning can produce a torque of $794$ ft$-$lbf$.$ What is that torque in N$-$m $($Newton$-$

meters$)?$

$9.$ AChevy Volt has a peak power of $149$ Hp$.$ What is the peak power in kJ$/$s$?$ What is the peak

power in ft$-$lbf$/$sec$?$

$10.$ The expected temperature today is $33\mathrm{.}0\backslash$deg F$.$ What is the temperature in Celsius? In Kelvin? In

Rankine?
