a. 180 in^3 to L
b. 750 ft-lbf to kJ
c. 75.0 hp to kW
d. 2500.0 lb/h to kg/s
e. 120 psia to kPa
f. 120 psig to kPa
g. 300 ft/min to m/s
h. 125 km/h to miles/h
i. 6000 N to Ibf
j. 6000 N to ton

Answer 1

The answers are below

Step-by-step explanation:

a. 180 in^3 to L

1 in³ = 0.0164L

180 in³ =
`180\ in^3*(0.0164\ L)/(1\ in^3)= 2.95\ L`

b. 750 ft-lbf to kJ

1 ft-lbf = 0.00136 kJ

750 ft-lbf =
`750\ ft-lbf *(0.00136\ kJ)/(1\ ft-lbf) =1.02\ kJ`

c. 75.0 hp to kW

1 hp = 0.746 kW

75 hp =
`75\ hp*(0.746\ kW)/(1\ hp)=55.95\ kW`

d. 2500.0 lb/h to kg/s

1 lb/h = 0.000126 kg/s

2500.0 lb/h =
`2500.0\ lb/h*(0.000126\ kg/s)/(1\ lb/h) =0.315\ kg/s`

e. 120 psia to kPa

1 psia = 6.89 kPa

120 psia =
`120\ psia*(6.89\ kPa)/(1\ psia) =826.8\ kPa`

f. 120 psig to kPa

1 psig = 6.89 kPa

120 psig =
`120\ psia*(6.89\ kPa)/(1\ psig) =826.8\ kPa`

g. 300 ft/min to m/s

1 ft/min = 0.005 m/s

300 ft/min =
`300\ ft/min*(0.005\ m/s)/(1\ ft/min) = 1.5\ m/s\\`

h. 125 km/h to miles/h

1 km/h = 0.62 mph

125 km/h =
`125\ km/h*(0.62\ mph)/(1\ km/h) =77.5\ mph`

i) 6000 N to Ibf

1 N = 0.2248 lbf

6000 N =
`6000\ N*( 0.2248\ lbf)/(1\ N)=1348.8\ N`

j. 6000 N to ton

1 N = 0.000102 Ton-force

6000 N =
`6000\ N*( 0.000102\ Ton-force)/(1\ N)=0.612\ N`
