Consider a tank where a hot stream whose volumetric flowrate is 9h and temperature is th is mixed with a cold stream with flowrate qe and temperature tc. the exit flowrate is q and temperature is t. (a) derive the dynamic model of the process, i. e. a set of differential equations describing the evolution of the height h and temperature t with time. assume a nonlinear resistance for the outlet flow, and constant density and heat capacity. (b) derive the linearized model in deviation variable form. use the following no- tation to conform to a standard state space model: xi = h, 12 = t, uj = 4c and u2 = 9h.

zfoods? ok, pressure is used to keep the heat inside and to keep the food perfect.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

water and alcohols have similar properties because water molecules contain hydroxyl groups that can form hydrogen bonds with other water molecules and with alcohol molecules, and likewise alcohol molecules can form hydrogen bonds with other alcohol molecules as well as with water.
