Study the following and answer the questions that follow :
A gas cylinder can discharge gas at the rate of 1 cc/minute from burner A and at the rate of 2 cc/minute from burner B (maximum rates of discharge). The capacity of the gas cylinder is 1000 cc of gas. The amount of heat generated is equal to 1 kcal/cc of gas. However, there is wastage of the heat as per the following table :Gas discharge @ Loss of heat 0-0.5 cc/minute 10% 0.5-1 cc/minute 20% 1-1.5 cc/minute 25% 1.5 + cc/minute 30%
(include higher extremes)[1] If both burners are opened simultaneously such that the first is opened to 90% of its capacity and the second is opened to 80% of its capacity, the amount of time in which the gas cylinder, the amount of time in which the gas cylinder will be empty (if it was half full at the start) will be
(1) 200 minutes
(2) 400 minutes
(3) 250 minutes
(4) None of these[2] The maximum amount of heat with the fastest speed of cooking that can be utilized for cooking will be when
(1) the first burner is opened upto 50% of it’s aperture
(2) the second burner is opened upto 25% of it’s aperture
(3) Either (1) or (2)
(4) None of theselast reply by CpjJwWHV • 10 years ago • asked in NMAT
