Introduction In the design of engineering projects‚ one of the most important soil properties of interest to the soils engineer is permeability. To some degree‚ permeability will play a role in the design of almost any structure. For example‚ the durability of concrete is related to its permeability. In designs that make use of earthen materials (soils and rock‚ etc.) the permeability of these materials will usually be of great importance. Soils are permeable (water may flow through them)

OBJECTIVE The main purpose of this experiment is:- i. To demonstrate the working principles of industrial heat exchangers ii. To investigate the efficiency of the heat exchanger in parallel and counter flow arrangements 1.0 INTRODUCTION A heat exchanger is equipment in which heat exchange takes place between 2 fluids that enter and exit at different temperatures. The main function of heat exchanger is to either remove heat from a hot fluid or to add heat to the cold fluid. The direction

The net force F = ΔP.A that acts on the ball is from the high pressure area(surrounding) to the low pressure area(above the fan) which makes the ball return to its initial position. Recorded air velocity = 5.4 +/- 0.5 m/s. Air density = 1.3 kg/m3 Diameter= (5.040 +/- 0.005) ×10-2m [pic]=[pic] [pic]= [pic]=[pic]= 1.6×10-5 m2 Ball area= (7.980 +/- 0.016)[pic]m2 Ball mass = (3.30 +/- 0.05)[pic]kg [pic] Now F of air resistance equals the ball’s weight since it is just lifted above
