The value of the rugosity co-efficient depends on the nature of the bed and the bank of the stream and proper care is required to be taken in selecting the right value of this co-efficient in order to get the correct discharge. Some values of the rugosity co-efficient, n, are given in table below for various types of surface conditions.

Nowadays lots of software tools are available in market to take care about the lengthy calculations. most of the cases a mechanical design engineer only needs to put input and the software tools give the output in desired format. these tools definitely help to drastically reduce the design time. in this article on mechanical design tutorial today i will talk about design of a simple l ...
Drains. to determine the design area for a pitched roof, table 1-1 is used. to determine the design area multiply the plan area by the factor in b column these areas are then divided by the proper factor given in table 1-2, thus obtaining the required area in square inches square mm for each downspout. from table 1-3 select the downspout ...
Chutes and drop spillways entrances-weirs weirs e.g., fig. 1 are the inlet sections of chutes and drop spillways, which are often required to drop water over steep sections of the landscape where flow velocities would be too erosive for an earth or vegetated channel. the flow through a weir, q, is described by the weir equation 2 3
