True conditions
Efficiency of Heat Exchanger are as below:
the heat exchange process between two fluids with different temperatures using solid walls occurs in various engineering applications. The tool to achieve this exchange is a heat exchanger. Some applications like air conditioning, power generation, waste heat recovery, and chemical processing use this device.
The basis of the work of a heat exchanger is that the hot fluid enters the heat exchanger at temperature T1 and its heat capacity is Chot. Also, the cold fluid with the heat capacity of Ccold enters temperature t1; in the meantime, the hot fluid loses its heat, and its temperature drops to T2. It delivers heat to the cold fluid to increase its temperature to t2 and leave the heat exchanger at this temperature.

Answer:
B electricity could not be distributed through power lines to people's homes
Answer:

Explanation:
From the question we are told that:
Weight 
Altitude
Let
Radius of Earth 
Gravity 
Generally the equation for Gravity at altitude is mathematically given by


Therefore
Weight at sea level


Weight at 6.33 altitude


Therefore



What is the weight? The weight of a 890 kg car is:
8727.9185 newtons
or
0.981057067 tons force
or
31393.8261 ounces force
