A spherical pressure vessel of 8.0 meter diameter is used to store liquid nitrogen gas at -40°C. An insulation with a thermal conductivity of 0.085 W/m-K and thickness 350 mm is applied to the tank to reduce the heat transfer. a) Determine the radial position in the insulation layer at which the temperature is 0°C when ambient air temperature is 20°C and the convection coefficient is 6 W/m²K. b) Repeat the same problem by considering contact resistance between sphere and the insulation of 0.2 K/W.

explanation:

d would be the most obvious choice to this question. leaders are supposed to herd their underlings like a shepherd to sheep. a leader should also listen to others when they are talking to one other to gain a better understanding of their mission and surroundings.

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.
