Suction lift: • It exists when the source of supply is below the centerline of the pump. • It is the distance between the centerline of the pump to the free level of the liquid to be pumped.
Speed of a boat in still water is 15 kmph and speed of stream is 12 kmph. A man rows to a place at a distance of 81 km and come back to starting point. ...
A motor boat goes downstream from point A to B ,which is 36 km away from point A, and then returns to A. If actual speed of the boat in still water is 7...
A boat takes half the time to move a certain distance downstream than upstream. the ratio of the boat's speed in still water and that of the current is.
The speed of the boat in still water is 10 km/hr and the speed of the stream is 5 km/hr. A boat goes 75 km downstream with its usual speed but at the ti...
A man can go on a motor boat with a speed of 25 km/hour in still water to a certain upstream point and come back to the starting point in a river which ...
The speed of current is 30 km/hr. If the speed of the boat in still water had been 13 km/hr more than the original speed then it would take 7.5 hours to...
A boat can travel 42 km downstream in 60 min. The ratio of the speed of the boat in still water to the speed of the stream is 5: 2. How much time will t...
A boat can cover 210 km in downstream in 10 hours and 160 km in upstream in 8 hours. Find the distance travelled by the boat in still water in 6 hours.
The time taken by a boat to travel a certain distance downstream is in the ratio 4:5 compared to the time taken to travel the sam...
The ratio of downstream speed to upstream speed of a boat is 5:3. If the boat can cover 160 km in still water in 10 hours, then find the difference betw...
