1
Q
What is flow rate dependent on?
A
- Directly proportional to r^4 and ∆Pressure
- Indirectly proportional to viscosity
2
Q
What has higher energy: microwaves or X-rays?
A
Microwave has lower energy and longer wavelength
3
Q
Surface tension
- Units
- Relation to temperature
A
Tendency of liquid to resist external force
- Energy/area
- Decreases as temperature increases
4
Q
Work done by liquid
A
P∆V
- Area under pressure-volume curve
5
Q
Imine
A
C=N
6
Q
Log(-5)
A
10^-5
7
Q
Velocity of sound equation
A
v = √B/rho
- Solid v > liquid v > gas v
- Stiffer object = faster sound
8
Q
Magnetic field strength
A
β = µoI/2r
- uo = permeability of space
- I = electrical current
9
Q
Equation of continuity
A
Q (constant) = A1v1 = A2v2
10
Q
Volume flow rate
A
Q = Av = V/t
11
Q
Viscous force
A
Fv = nAv/d
- Decreases as temperature increases
12
Q
Poiseuille’s Law
A
V/t = ∆Pr^4/nL
13
Q
Venturi effect: constrict pipe => ____
A
Increased velocity => decreased pressure
14
Q
Surface tension
A
T = F/L*Temp
15
Q
Water + ester
A
COOH and OH
