길이 50 m, 넓이 15 m, 평균깊이 2 m인 폐기물 처리장에

밀도가 85.31 lbm/ft3인 폐기물이 들어있다.

단일 차원 방정식을 이용하여

이 처리장의 폐기물 무게를 lbf의 단위로 계산하라.

A waste treatment plant with a length of 50 m, a width of 15 m,

and an average depth of 2 m contains waste with a density of 85.31 lbm/ft3.

Calculate the weight of waste from this treatment plant in lbf

using a single dimensional equation.

> 1 ft = 0.3048 m (exactly, 정확한 값)

▶ gravitational acceleration. 중력 가속도

> exactly as 9.80665 m/s2 (about 32.174 ft/s2)

“Standard gravity” is defined as exactly 32.174049 ft/s2,

but usually rounded to 32.174 ft/s2.

---> 1 lbf = 32.174 lbm•ft/s2

(50×15×2 m3) (1 ft / 0.3048 m)^3 (85.31 lbm/ft3) (32.174 ft/s2) (1 lbf / 32.174 lbm•ft/s2)

= (50×15×2) (1 / 0.3048)^3 (85.31) (32.174) (1 / 32.174)

= 4519041 lbf

답: 4.519×10^6 lbf

[참고] A waste treatment pond is 50 m long and 15 m wide, and has an average depth of 2 m. The density of waste is 85.3 lbm/ft3. Calculate the weight of the pond contents in lbf, using a single dimensional equation for your calculation.

(50×15×2) (1 / 0.3048)^3 (85.3) (32.174) (1 / 32.174)

= 4518512 lbf

= 4.52×10^6 lbf
