A mass airflow sensor is used to determine the mass of air entering the engine. The air mass information is necessary to calculate and deliver the correct fuel mass to the engine. Air is a gas, and its density changes as it expands and contracts with temperature and pressure. In automotive applications, air density varies with the vehicle's operating environment, and is an ideal application for a mass sensor. (See stoichiometric, ideal gas law, and density.)

There are two common types of mass airflow sensors in usage on gasoline engines. The..............etc

Net radiation heat transfer between any two surfaces can be expressed as

Qi→j = Ai Ji Fi→j – Aj Jj Fi→j (W) (Çengel, Heat and Mass Transfer, p 729 (13-28))

It is common to assume the surfaces of an enclosure to be opaque, diffuse and gray. That is surfaces are nontransparent, they are diffuse emitters and diffuse reflector, and their radiation properties are independent of wavelength.
For thermal equilibrium net heat transfer becomes zero.
Qi→j =0 and rearranging the equation

Ai Ji Fi→j – Aj Jj Fi→j =0

Jet impingement heat transfer – Part I: Mean and root-mean-square heat transfer and velocity distributions
Abstract
Impinging jets provide a means of achieving high heat transfer coefficients both locally and on an area averaged basis. The currentwork forms the first stage of a two part investigation of heat transfer distributions from a heated flat surface subject to an impinging airjet for Reynolds numbers from 10,000 to 30,000 and non-dimensional surface to jet exit spacing, H/D, from 0.5 to 8. In the present paper,the rel..............etc

HEAT AND MASS TRANSFER


1. Define Heat transfer?
Heat transfer can be defined as the transmission of energy from one region to another region to
temperature difference.

2. What are the modes of heat transfer?
1. Conduction
2. Convection
3. Radiation

3. What is conduction?
Heat conduction is a mechanism of heat transfer from a region of high temperature to a region of
low temperature with in a medium (Solid, liquid or Gases) or diffe..............etc
