TITLE Bernoulli ’s Principle OBJECTIVE experiment is done to investigate the validation of the Bernoulli’s equation and also to measure pressure distribution along venture tube. INTRODUCTION This experiment is carried out to investigate the validity of Bernoulli’s theorem when applied to the steady flow of water in tapered duct and to measure the flow rates and both static and total pressure heads in a rigid convergent/divergent tube of known geometry for a range of steady flow rates.

Reaction Time Reaserch Question: To design on investigation into stimuli ( sight/sound ) that may affect reaction time ( time taken for a response to occur in reaction to a stimulus.) Background information: Humans perceive their outside world through five senses: touch ‚sight‚ taste‚ smell and sound. The reason why we have the 5 major senses is to detect and discriminate among the signals that comes from our environment. These signals carry information necessary for us to support our vital
