Fluid

Question 1

Density

Answer 1

P=m/v

Question 2

Specific Volume

Answer 2

v=1/p

Question 3

Specific Weight

Answer 3

y=pg

Question 4

Specific gravity

Answer 4

SG=p/pw

pw=1000

Question 5

Shear stress

Answer 5

τ=F/A
or
τ=μdv/dy

Question 6

Viscosity

Answer 6

μ=τ/(dv/dy) = (f/a)/τ/(dv/dy) = mass/(length x time)

Question 7

kinematic viscosity

Answer 7

v=μ/p

Question 8

Pressure

Answer 8

P=F/A

Question 9

Answer 9

F=ma

Question 10

Resolving Forces

Answer 10

ΔP/ΔL=-pgcosΘ

Question 11

Pressure Guage

Answer 11

Pgauge=pgh

Question 12

Pressure Guage Height

Answer 12

h=Pguage/pg

Question 13

Velocity

Answer 13

Vmean=Q/A

Question 14

Mass Flow Rate

Answer 14

Q=(p)(a)(v)

(p)(a)(v)1=(p)(a)(v)2+increase in mass

Question 15

Answer 18

PA*V

Question 19

total energy per unit w

Answer 19

(v^2)/2g + h + p/pg = constant

Question 20

Bernoulli Equation

Answer 20

((v^2)/2g + h + p/pg)1 = ((v^2)/2g + h + p/pg)2

Question 21
