Question

the length of rectangular tank 100m its breadth is 80 m if water is flowing through a square sluiceof area 1 metre square at 40 metres per minute then the time taken to fill the tank to depth of 2mts is

Answer 1

Answer:

400 minutes = 6 hour 40 minutes

Step-by-step explanation:

length (l)= 100; Breadth (b) = 80; height (h)= 2

then volume(v)= l x b x h

                       = 100x80x2

                       = 16000 m^3

then time taken to fill it 2m depth is= 16000/ (1x40)

                                                           = 400 min

                                                            = 6hr 40min
