Hydraulics and Fluid Mechanics Laboratories
Water networks and drainage channels are considered as one of the most important infrastructure component for any city/civilization. The hydraulics subject is focusing on that side of infrastructure requirements; the hydraulics laboratory in the civil engineering department is fully equipped with all the facilities, which always facilitated to be in the services of society for the use of water for domestic, commercial and agricultural purposes through supply networks and drainage channels.
In hydraulics laboratory there is a range of experimental setups through which students are given a very good demonstration to understand the various methods of measurement of flow rates, capacity & velocity of water in tanks, closed pipes and open channels. In addition, in this laboratory, students get an experience to understand the fluid properties like surface tension, temperature, viscosity and they get a practical experience of measurement of these properties, which are very important for the selection of pumps, pipes and its specifications like material, size & slope. It is quite useful for design of drainage channels and open channel.
In Hydraulics laboratory, we use to find and verify the difference between the theoretical calculations and actual quantities of flow and its parameters in a pipe network or open channels. By using the experimental setups like losses through closed pipes, flow through orifice meter, flow through venturimeter or flow in open channels, we get the coefficient of various parameters like discharge, velocity etc. These coefficients represent a realistic relationship between theoretical calculations and actual observations, which ultimately enables us to find an accurate and appropriate estimate of parameters like flow rate, capacity, velocity, pressure, slope etc. to calculate the required dimensions and hydraulic specifications for the desired application of civilian and noncivilian purposes/projects.
Hydraulics laboratory, through its water group staff, contributes its services in the society by conducting the various listed experiments during the studies and research programs, these studies include individual studies or others supported by King Abdul Aziz City foe Science & Technology (KACST) and other government agencies. In addition, this modern laboratory has the facilities for the students in the department to get a good chance to experience and practice the recent technologies of hydraulics and fluid mechanics through experimental setups, which will lead them towards the opportunities to work in their society in different fields for the betterment of society in a scientific manner.
