Answer:
4.5kg/min
Explanation:
Given parameters

if we take
The mass flow rate of the second stream = 
The mass flow rate of mixed exit stream = 
Now from mass conservation


The temperature of the mixed exit stream given as

Therefore the mass flow rate of second stream will be 4.5 kg/min.
Answer: It is a term of heat transfer process in which fins are surface that are the extension of the object to work for the heat exchangers to increase the heat exchanging rate.
Explanation: Fins are considered to help the heat exchanger surface to lead the process of heat transfer by increasing the are of the surface which is exposed to the surroundings. Fins work really well with materials having high thermal conductivity and will be more effective. They are preferred because they increase the rate of exchange of heat by increment in the convection.
Answer:
A driver is an independent software application that is used to configure communication between a personal or industrial computer and a hardware device
Answer:
c. Alto módulo de elasticidad
Explanation:
The correct answer to the given question is c. Alto modulo de elasticidad
A Youngs modulus measures the resistance of any material to elastic deformation. It is basically the ratio of the stress applied to a body to the results of the stress which is the response of the body over the pressure applied. This is to test the stiffness of any material and most of time the material stays constant over stressing.
