Answer: Absolutely. Boiler explosions are a huge hazard, whether stationary or on a train engine. These days boiler construction is much better understood, and highly regulated, so it’s a pretty rare occurrence, but a century ago, they were pretty common.
There was even a stunt staged in 1896 where two old steam locomotives (and trains) were crashed into each other. Despite the expectations that the boilers would not explode, they did, and killed a couple of people and injured many more.

Explanation:
In a black box experiment, when the amount of material exiting a closed system is less than the amount of material entering the system, what conclusion can the experimenter make?
A.
that material remained in the system
B.
that material was lost
C.
that it will be difficult to make an accurate measurement
D.
that parts of the system need to change
When the material that exits is lesser in amount than that of the entering material in a black box experiment, the parts of the system need to be changed.
What happens in a black box experiment?In a black box experiment, the experimenters need to make assumptions regarding the drawing of conclusions. One such conclusion is the amount of material that exits.
If such amount is lesser than the one that enters the system, such experiment concludes that it is the time to change the parts of the system.
Hence, option D holds true regarding the black box experiment.

Water is chilled by brine in a counter-current heat exchanger. If the flow rate of the brine is 2 kg/s and that of the water is 1 kg/s, estimate the temperature to which the water is cooled if the brine enters at -4°C and leaves at 12°C. The water enters the heat exchanger at 28°C. If the heat transfer surface area of the heat exchanger is 5.50m^2, determine the overall heat transfer coefficient. Take the mean heat capacity of brine and water to be 3.4 kJ kg^-1 K^-1, and 4.2 kJ kg^-1 K^-1 respectively.
I need help with this asap please. Thank you very much. I will tag anyone who answers as brainliest.
Answer:The area of heat exchanger
Explanation:
Given that
Brine heated from 10°C to 35°C and water cools from 60°C to 45°C.
Lets take these are act as counter flow heat exchanger.
So
As we know that
Here
LMTD=29.7°C.
for water
0.3 x 4.187 x 15 = 950 x A x 29.7
So the area of heat exchanger
