Answer 1

Answer:

The answers are below

Explanation:

a. 180 in^3 to L

1 in³ = 0.0164L

180 in³ = $180\ in^3*\frac{0.0164\ L}{1\ in^3}= 2.95\ L$

b. 750 ft-lbf to kJ

1 ft-lbf = 0.00136 kJ

750 ft-lbf  = $750\ ft-lbf *\frac{0.00136\ kJ}{1\ ft-lbf} =1.02\ kJ$

c. 75.0 hp to kW

1 hp = 0.746 kW

75 hp = $75\ hp*\frac{0.746\ kW}{1\ hp}=55.95\ kW$

d. 2500.0 lb/h to kg/s

1 lb/h = 0.000126 kg/s

2500.0 lb/h = $2500.0\ lb/h*\frac{0.000126\ kg/s}{1\ lb/h} =0.315\ kg/s$

e. 120 psia to kPa

1 psia = 6.89 kPa

120 psia = $120\ psia*\frac{6.89\ kPa}{1\ psia} =826.8\ kPa$

f. 120 psig to kPa

1 psig = 6.89 kPa

120 psig = $120\ psia*\frac{6.89\ kPa}{1\ psig} =826.8\ kPa$

g. 300 ft/min to m/s

1 ft/min = 0.005 m/s

300 ft/min = $300\ ft/min*\frac{0.005\ m/s}{1\ ft/min} = 1.5\ m/s$

h. 125 km/h to miles/h

1 km/h = 0.62 mph

125 km/h = $125\ km/h*\frac{0.62\ mph}{1\ km/h} =77.5\ mph$

i) 6000 N to Ibf

1 N = 0.2248 lbf

6000 N = $6000\ N*\frac{ 0.2248\ lbf}{1\ N}=1348.8\ N$

j. 6000 N to ton

1 N =  0.000102 Ton-force

6000 N = $6000\ N*\frac{ 0.000102\ Ton-force}{1\ N}=0.612\ N$
