Energy Considerations in Open Channel Flow

OBJECTIVE

To determine the relation between specific energy and water depth for flow over a hump located in a horizontal channel.

INTRODUCTION

APPARATUS

A schematic diagram of the apparatus is shown in Figure (4.16). The flume has rectangular cross section and incorporates a triangular hump on the bed. The water supply is derived into the channel by a centrifugal pump. The rate of flow can be controlled by a gate valve. The depth of water in the flume can be measured with a point gauge
