. If a pipe can fill the tank within 6hrs.But due to leak it takes 30 min more. Now the tank is full then how much time will it take to empty the tank throught the leak

• 1/6+1/t=1/6.5
  thn t=-78 but for outflow - is neglected

• 30min of water inflow = 6.5hrs of water outflow
  
  6hrs of water inflow = 6.5*12=78hrs
  
  ans=78hrs

• 78 hrs ans
  by A (pipe) time ---------- 360 mins
  in one min by A = 1/360
  now by A (pipe) by B (leak) time-------390
  by (A+ B) in one min = 1/390
  by (B) leak = 1/360 - 1/390=( 390- 360)/360*390 =30/360*390 total time to
  empty the tank= 360x390/30x60 = 78 hours

• there's a formula:
  time to leak completely = (-6.5 * 6)/(6.5-6)
• 12 years agoHelpfull: Yes(4) No(1)
• 78 minutes, if we neglect physics
• 7 years agoHelpfull: Yes(0) No(0)
• Assume speed of inflow = t lit/hr and outflow through leak = y lit/hr
  total capacity is constant
  6.5(t-y ) = 6(t);
  13y = t;
  with t, it took 6hours
  for t/13, it takes 13* 6 = 78 hours
