Measured inlet and outlet temperatures of the fluids flowing through a heat exchanger are T subscript 1 equals 80 to the power of 0 F space space space space space space T subscript 2 equals 80 to the power of 0 F space t subscript 1 equals 25 to the power of 0 F space space space space space space t subscript 2 equals 40 to the power of 0 F space What type of heat exchanger is this

True.it is better to buy a washer with a higher efficiency rating

Ais the answer hope this

Because they're in different places for this the temperature varies.

Sounds propagates through some kind of medium. usually it's air, but it goes just as well through solid objects like walls, windows etc. a soundwave will compress the (air)molecules in front of it, and if this increased density wave hits your ears, you register it as sound. solid objects like walls are a lot denser than air, this means that they will damp a wave, but also carry it easier.
