Given Information:
Inlet Temperature of hot air= Th₁ = 450K
Exit Temperature of hot air = Th₂ = 350K
Inlet Temperature of cold air = Tc₁ = 300K
Volume flow rate of hot air = vh = 0.02 m³/s
Volume flow rate of cold air = vc = 1 m³/s
Required Information:
Exit Temperature of cold air= Tc₂ = ?
Answer:
Exit Temperature of cold air = Tc₂ = 302 °C
Explanation:
In a heat exchanger, the cold air absorbs heat that is lost by the hot air,
Heat absorbed by cold air = Heat lost by hot air
Therefore, the exit temperature of the cold air is 302 °C or 575K
Note:
m = ρv
Where ρ is density of air and v is the volume flow rate and m is the mass flow rate.
cp is the specific heat capacity of air.
Democritus was the first contributor to the atomic theory
The current in the wire has created a magnetic field with its north pole at the top of the rod. A magnetic field influences electric currents.
<h3>What is a magnetic field?</h3>
A magnetic field is a type of field that influences the position and direction of the electric current.
The magnetic field also refers to the one where magnetic forces act to shape an electrical current.
The only material and/or body capable of altering an electrical current in a magnetic field is the presence of another magnetic field.
