Thermal Fluids System and Transport Phenomena"*
​

 Thermal fluid systems are heating systems in which the thermal fluid, such as glycol or thermal oil, is heated and then recirculated supplying indirect heat to process equipment, materials, and systems. Because they supply indirect heat, thermal fluid systems minimize the risk of burns or heat damage to equipment.

 Transport phenomenon, in physics, any of the phenomena involving the movement of various entities, such as mass, momentum, or energy, through a medium, fluid or solid, by virtue of nonuniform conditions existing within the medium.

ur welcome and please mark me brainliest? O///O

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s
