A rectangular greenhouse measures $20$ m in width by $250$ ft in length. What is the floor area of

the greenhouse in ac$?$

Water flows from a hose at a rate of $10\mathrm{.}2ga\frac{l}{m}in.$ The hose is used to flood the floor of the

greenhouse in Problem $1($rectangular greenhouse measures $20$ m in width by $250$ ft in length$).$

If the desired depth of water is $4\mathrm{.}0$ in $,$ how long $(min)$ will it take to flood the floor?

The owner of a right circular cylindrical storage tank $($supported parallel to the ground on

cement piers$)$ wants to paint the exterior of the tank. A gallon of paint covers $200f{t}^2.$ If the tank

is $3\mathrm{.}0$ m in diameter and $5\mathrm{.}0$ m in length, how many $L$ of paint should be purchased to paint the

entire exterior of the tank? Note: Both ends of the tank must be painted and assume the area

of contact between the tank and piers is negligible.

A compost turner is used to enhance biological activity within rows of composted municipal yard

waste. A commercial facility consists of $10\mathrm{.}0$ ha compacted earthen composting pad. Assume the

compost turner operates at $3\mathrm{.}5m\frac{i}{h},$ and that the efficiency of the machine and operator is

$75\%.$ The compost rows are spaced $15\mathrm{.}0$ ft apart. How long $($hrs$.)$ will it take turn the compost?

The University operates its bus fleet using Compressed Natural Gas $($CNG$).$ Gas is transferred to

the buses at a pressure of $3,600l\frac{b_f}{i}{n}^2.$ One Gallon of Gasoline Equivalent $($GGE$)$ is equal to $0\mathrm{.}51$

$f{t}^3$ of CNG at $3,600l\frac{b_f}{i}{n}^2.$ Assuming the University buses have a tank size of $60$ GGE $,$ what is the

overall volume of the tank in L$?$
