Chapter 17, Problem 1RQ
Define an electrolyte and its role in battery operation.
Expert Solution & Answer
To determine
The role of electrolyte in a battery.
Explanation of Solution
A battery is a primary source of electrical power in an auto vehicle. It converts the chemical energy into electrical energy. A battery consists of two electrode or plates of which one is considered as a cathode and other an anode and an electrolyte solution.
An electrolyte is a chemical solution having both the cathode and anode plates submerged into it. The electrolyte in a battery reacts with the metal of the submerged plates. This chemical reaction causes a lack of electrons on a positive plate and an excess on negative. Due to which the electrons moves and the current starts flowing.

A window in a tall building experiences a horizontal wind flow parallel to the surface at a velocity of 8 m/s. The window
measures 2 m high, 1.5 m wide and 6.5 mm thick. The transition from the building wall to the window glass surface is
not smooth. The window casement that surrounds the edge of glass pane is raised 10 mm above the surface of the glass
and adjacent wall structure. Inside the building, the air temperature and heat transfer coefficient for the interior surface
are 21 °C and 9 W/m² K respectively. The window has a uniform thermal conductivity of 1.4 W/m K. If the outdoor air
temperature is 5 °C, determine the rate of convective heat loss from the window. Develop a thermal resistance network
for the window system. Please state and justify all assumptions. Neglect any conduction through the casement.
Assume the following air properties: kair =0.0248 W/m K, v= 14.20 x 106 m²/s, Pr = 0.712.
