Water is poured from a height of 10m into a mepty vessel at the rate of 1 litre per second . If the weight of the vessel is 10 kg ten th weight indicated at time t=60s will be

Pipe A can fill a tank in 2 hours at the rate of the 6 litres per minute. What is the capacity of the tank?

If two pipes function simultaneously,a reservoir will be filled in 12 hours.One pipe fills the reservoir 10 hours faster than the other.How many hours will the second pipe take to fill the reservoir?

The length,breadth and height of a cuboidal reservoir is 7m,6m and 15m respectively.8400 litre of water is pumped out from the reservoir.Find the fall in the water-level in the reservoir.

There are 100 million litres of fluoridated water in the reservoir containing a city\'s water supply, and the water contains 700 kg of fluoride. To decrease the fluoride content, fresh water runs into the reservoir at the rate of 3 million litres per day, and the mixture of water and fluoride, kept uniform, runs-out of the reservoir at the same rate. How many kilograms of fluoride are in the reservoir 60 days after the pure water started to flow into the reservoir?

Large fresh water reservoir is fitted with two types of feeder pipes- hot water pipes and cold water pipes. Six cold water pipes alone can fill the reservoir in 12 hours. 3 cold water pipes and 9 hot water pipes together can fill the reservoir in 8 hours.
