Flash and Fire Point of Bitumen
Bitumen is tested using the Pensky Marten test to determine its flash and fire point.

Flash Point
- The momentary flash was seen at a temperature of 200°C during the test.
- This indicates the flash point of the bitumen, which is the temperature at which it gives off enough vapor to ignite momentarily in the presence of a flame.

Fire Point
- The bitumen burned for at least 5 seconds at a temperature of 240°C during the test.
- This indicates the fire point of the bitumen, which is the temperature at which it sustains burning for at least 5 seconds.
Therefore, the flash point of the bitumen is 200°C, and the fire point of the bitumen is 240°C. So, option A is correct.

Flashpoint:

It is the lowest temperature at which the application of a test flame causes the vapors of the binder to catch an instant fire in the form of a flash under specified test conditions.
Two types of test apparatus may be used for conducting flash point tests on bitumen, namely the Pensky-Martens Closed Cup Tester and Open Cup Tester.
Here, In the bitumen test, momentary flash was seen at a temperature of 200° Celsius. So, the flash point is 200° Celsius.
If the bituminous binder is further heated to a temperature higher than the flash point, the binder material itself catches fire and continues to burn, the lowest temperature causing this condition is called the fire point.

Fire Point:

It is the lowest temperature at which the application of test flame causes the binder material to ignite and burn at least for five seconds under specified test conditions.
Here, bitumen burned for at least 5 seconds at a temperature of 240° Celsius. So, the fire point is 240° Celsius.

Important Points

The fire point is always higher than the flash point of a material.
Pensky-Martens open cup tester is used to determine the flash & fire point of the bituminous binders.

A wastewater stream in a city with flow rate 200 m3/s, discharges at a point into a river, which is fully saturated with oxygen and flowing at a rate of 2800 m3/s during the lean period with velocity of 25 cm/s. It was estimated that the critical deficit will occur at a location of 30 km downstream of the river from the point where wastewater starts mixing into river water. If the 5 days BOD of the wastewater at 30°C temperature is 350 mg/l and considering the temperature of the mix to be 20°C, then the critical oxygen deficit (in mg/L) will be _______. It is given that kDand kRat 20°C are 0.10 per day and 0.2 per day respectively. Correct answer is between '13.7,14'. Can you explain this answer?
