Question

ProblemSet4: Problem 1 Problem List Next (2 points) A water truck's tank has internal dimensions of 14 meters in length and 2 meters in diameter. If the truck's load of pure water is 80 percent of fuil capacity, how heavy is the load in pounds? Water's density is 62.4 Ib/ ft lbs In kilograms, what is the weight of the load if the truck carries liquid nitrogen instead of water? The liquid nitrogen's density is 0 808 g/ml kg Note: Preview My You have attempted this problem 1 time.

Explanation / Answer

Volume of tank = pi×r^2×h=3.14×1×1×14=43.96m^3

=1552.4ft^3(using 1m=3.28feet)

Volume of water=80/100×1552.4=1241.9ft^3

Density=62.4Ib/ft^3

Mass=62.4×1241.9=79731.26Ib

Volume of nitrogen =0.8×43.96m^3=35.16×10^3litre

Density=0.808g/mL=0.808kg/litre

Mass=0.808×35.16=28.42kg
