Pelton Steering wheel Lab

 Pelton Wheel Lab Dissertation

Title: Pelton wheel

Objectives:

1 . To get familiar with the working principle of Pelton Wheel. 2 . To determine the characteristics of Pelton Tire.

several. To determine the the best possible efficiency level.

Launch:

The pelton wheel is an extremely efficient behavioral instinct turbine developed by Lester Allan Pelton. The water plane shot the turbine cutting tool and the causes are broken into two shaped parts. As opposed to other turbine blade Pelton's paddle geometry was designed so that when the casing runs in ВЅ the speed of the water jet, and then the water is leaves with little strength.

Apparatus:

Pelton tire and stop watch.

Figure 1 ) Pelton tyre machine

Procedures:

1 . ) The pelton wheel machine is completely set up already.

2 . ) Now turn on the main power and start the pump. a few. ) The nozzle jet is pre-specified at fully opened placement. The water shot from the nozzle caused the wheel to rotate. 5. ) The speed is first established at 1200 rpm then the tire is permitted to run intended for 3 minutes pertaining to the movement rate to stable. your five. ) The belt is definitely attached to the pulley at the back of the Pelton wheel. Assure the belt is sitting properly for the groove of the pulley. 6th. ) Force 1, load 2, acceleration of the rotarion, pressure and water collection time for 20 liters are documented. 7. ) The load is definitely apply to the wheel by simply tighten the load nut and decrease the speed. almost 8. ) The values are recorded for each and every 100 rpm decrement of speed of the wheel right up until 800 rpm.

Results:

* Load (N) = F1 – F2

* Average speed (rad/s) = Average speed (rpm) x 2 ПЂ/60

2. Torque (NВ·m) = Fill (N) times radius of wheel (0. 026 m)

* Input power (W) = Pressure (N/m2) x Flow price (m3/s)

5. Output power (W) = Torque (NВ·m) x Typical speed (rad/s) * Efficiency = (Output Power as well as Input Power) x 100%

Discussion:

1 .

2 .

Based on the graph of output electric power against rate, the trend is really as the speed improves, the output electric power decreases. The same trend adopted for the graph torque capacity against...
