cannot exit from while loop

Question

My code is stuck within while-loop. It keeps looping back to the Backup_power (refer to the image below).

lowest = 38
puts 'Read Temperature:'
t = gets.chomp.to_f

if(t < lowest)
 lowest = t
end
while t<=80 || bpower=='on'
  puts 'Enter backup power (on/off):'
  bpower = gets.chomp

  if(t<50)
    puts 'Normal mode of operation'
  else
    if(t<=80 || bpower=='on')       
      puts 'On the fan'
    else
      puts'Turn off equipment'
    end
  end
  puts lowest
end

"Can somebodyy help me?" is not a precise enough error description for us to help you. What doesn't work? How doesn't it work? What trouble do you have with your code? Do you get an error message? What is the error message? Is the result you are getting not the result you are expecting? What result do you expect and why, what is the result you are getting and how do the two differ? Is the behavior you are observing not the desired behavior? What is the desired behavior and why, what is the observed behavior, and in what way do they differ? — Jörg W Mittag

You've posted your code. Now can you say where in the code you're getting the problem. Is there an error message? What does it say? — Sagar Pandya

You are almost there!
The problem is you did not include the Read Temperature inside the loop. So how do you intend to read the new temperature?

I will give you a hint:

lowest = 38
t=0
bpower="on"

while t<=80 || bpower=='on'
  Read Temperature
