Energy Units

Question 1

1 Btu =

Answer 1

= 252 cal
= 778 ft/lbf
= 1055 J

Question 2

1 J

Answer 2

= 10^7 dyne*cm

Question 3

1 kW

Answer 3

= 1000 J/s
= 1.34 hp
= 239 cal/s

Question 4

Dynamic Viscosity (µ):
1 poise

Answer 4

= 100 cP
= 1 dyne*s/cm^2
= 1 g/(cm*s)
= 1/10 Pa*s
= 1/10 N*s/m^2

Question 5

water absolute viscocity

Answer 5

at 20 C viscosity = 1 cP

Question 6

Kinematic Viscosity (ν)
1 stoke (St) =

Answer 6

= 100 cSt = 1 cm2/s
= 100 mm2/s
= 10-4 m2/s

Question 7

Torque: 1 Nm =

Answer 7

= 1 kg⋅m2/s2

= 0.738 lbf-ft (pound-foot)
