AA/NA Observation Andrea Ross February 15‚ 2011 Health class For my observation. I attended an NA meeting. It was in Hemet CA‚ on a Tuesday night. The building was called “Red Dog Group”. I had walked in‚ and told the lady at the front desk that I was here to sit in on a meeting and observe it for my health class. She said”Of course you can‚ just wait here for about another 10 minutes

CENTRIFUGAL PUMP A centrifugal pump converts the input power to kinetic energy in the liquid by accelerating the liquid by a revolving device - an impeller. The most common type is the volute pump. Fluid enters the pump through the eye of the impeller which rotates at high speed. The fluid is accelerated radially outward from the pump chasing. A vacuum is created at the impellers eye that continuously draws more fluid into the pump. The energy created by the pump is kinetic energy according the

Centrifugal pump A centrifugal pump is a rotodynamic pump that uses a rotating impeller to increase the pressure of a fluid. Centrifugal pumps are commonly used to move liquids through a piping system. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller‚ flowing radially outward into a diffuser or volute chamber (casing)‚ from where it exits into the downstream piping system.[1][2] Centrifugal pumps are used for large discharge through smaller

CENTRIFUGAL PUMPS Introduction A centrifugal pump is a rotodynamic pump that uses a rotating impeller to create flow by the addition of energy to a fluid. Centrifugal pumps are commonly used to move liquids through piping. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller‚ flowing radially outward into a diffuser or volute chamber (casing)‚ from where it exits into the downstream piping.

This experiment was conducted under room temperature. The motor was first adjusted to 3000 rpm and the input valve which was used to control the input pressure was adjusted in 0.1bar steps.

AUTOMATIC WATER PUMP CONTROLLER The automatic water pump controller is used to control the water pump motor. The motor gets automatically switched on when water in the overhead tank (OHT) falls below the lower limit. Similarly‚ it gets switched off when the tank is filled up. Built around only one NAND gate IC (CD4011)‚ the circuit is simple‚ compact and economical. It works off a 12V DC power supply and consumes very little power. The circuit can be divided into two parts: controller circuit and
