Working in the laboratory

HND Civil Engineering students carryingout a number of experiments in small groups.

Discharge over a rectangular notch weir

Students in the back ground are discussing the finer points of calculating flow rate through the flume. The student in the foreground is mastering the technique of sleeping while standing up.

You did what??

A heated discussion on how to measure the depth of water flowing over the weir. The guy in the middle is still fast asleep!!

Adjusting the flow through the flume.

Here the degree of adjustment to the control valve on the left is being discussed by several of the team members.

Friction Loss along pipes

This group is trying the determine the amount of friction loss along a specified length of small diameter pipe. A specific quantity of water is collected in the blue bin and the time it takes to fill is recorded. Pressure readings are being taken on the head difference manometers against the window.

Hydraulics Work Bench

This group are working on a self-contained hydraulics work bench, to calculate the coefficient of discharge of a venturi and orifice plate meter. The student on the left is also mastering the technique of sleeping while standing up.

Adjusting the flow through the apparatus

Several of the students are recording the flow through the apparatus by timing a quantity of water into a weigh bin and the others are making adjustments to the control valve and writing down the readings taken. The guy in the front still looks as though he is asleep.

Pressure readings on the Manometer tubes

The pressure levels in the apparatus are determined from the pressure difference manometers and these students are taking the readings off the manometer.
