Answer:
(a) dynamic viscosity = 
(b) kinematic viscosity = 
Explanation:
We have given temperature T = 288.15 K
Density 
According to Sutherland's Formula dynamic viscosity is given by
, here
μ = dynamic viscosity in (Pa·s) at input temperature T,
= reference viscosity in(Pa·s) at reference temperature T0,
T = input temperature in kelvin,
= reference temperature in kelvin,
C = Sutherland's constant for the gaseous material in question here C =120

= 291.15
when T = 288.15 K
For kinematic viscosity :


AnsweR Viciously comes from the adjective vicious, which originally meant "of the nature of vice, or wicked." The Latin root, vitiosus, means "faulty, defective, or corrupt."

The tool you would use are brake line wrenches.
Answer:
Explanation:
(c). looking for the radiation of the collector is given thus
C = 0.095 + 0.04 sin [360/365(n-100)] = 0.095 + 0.04 sin [360/365(1-100)]
C = 0.05535
∴ Diffuse radiation of the collector Idc = C*Ib + (1+cosσ/2)
Idc = 0.5535 * 908.7 (1+cos40/ 2) = 44.41 W/m²
Idc = 44.41 W/m²
