Awall with a surface area of 10 m2 is 2.5 cm thick. the inner surface temperature of the wall is 4150c, but the outer surface is much cooler. the heat loss through the wall is 3 kw, and the thermal conductivity is 0.2 w/m-k. a. what is the temperature of the outer surface of the wall? list all applicable assumptio

650.65 K or 377.5°C

Explanation:

Area = A = 10 m²

Thickness of wall = L = 2.5 cm = 2.5×10⁻² m

Inner surface temperature of wall = = 415°C = 688.15 K

Outer surface temperature of wall =

Heat loss through the wall = 3 kW = 3×10³ W

Thermal conductivity of wall = k = 0.2 W/m K

Assumptions made here as follows

Considering the above assumptions we use the following formula

∴ The temperature of the outer surface of the wall is 650.65 K or 377.5°C

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
