THE ADVANTAGES OF INDUCTION MOTORS OVER SYNCHRONOUS MOTORS
1. Induction motors can be self-started but synchronous motor is not self-starting.
2. Induction motor does not require any external excitation to run while synchronous motor requires an external D.C to run.
3. Induction motors are less expensive and user friendly unlike synchronous motors which are expensive and complicated to use.
4. Induction motors are used in MOST of the rotating or moving machines like grinders while synchronous motors are used ONLY when very low speed performance is required.

- Into a stream, with no trace of salt initially, a salt with a concentration of 20 mg/cc is introduced at a constant rate of 2...(Solved)
Into a stream, with no trace of salt initially, a salt with a concentration of 20 mg/cc is introduced at a constant rate of 2 litres per minute. The samples collected at a downstream section sufficiently far away indicated an equilibrium salt concentration of 0.05 ppm. Determine the discharge in the stream from this data.

- The following data pertain to streamflow in a river at a given gauge station. The rate of rise in water surface elevation = 10.0 cm/h....(Solved)
The following data pertain to streamflow in a river at a given gauge station. The rate of rise in water surface elevation = 10.0 cm/h. the normal discharge for the river stage obtained from the steady flow rating curve = 150 m3/s. slope of the river bed = 3 x 10-4. Assume the velocity of the flood wave to be 2.5 cm/sec, compute the river discharge.

A drainage basin has an area of 210 km2. The average depth of rainfall received by it during a monsoon period is computed as 65 cm, while the runoff measured at its outlet during the same period is estimated to be 5.68 x 107 m3. Compute the depth of runoff. What percentage of rainfall has become runoff? If all this runoff volume is stored and used to irrigate a crop which requires 60 cm of water, how many hectares can be irrigated?

- The mean daily flows at a gauging station for a period of 7 days are 7, 27, 58, 41, 31, 20 and 13 m3/s respectively....(Solved)
The mean daily flows at a gauging station for a period of 7 days are 7, 27, 58, 41, 31, 20 and 13 m3/s respectively. What is the total volume of streamflow at the site in cumec-days(metres cubed per second.)? and in hectare-metres? What is the mean flow rate for the week? If the drainage area at the site is 100 km2, what is the runoff volume in cm?
