Answer:
A,B,D,E are wrong
(A) Heat exchangers are devices where two moving fluid streams are mixed together (B) Heat exchangers are devices where two moving fluid streams exchange mass (D) Heat exchangers are devices where two moving fluid streams exchange mechanical work without mixing together (E) There is no heat transfer between the two fluids of an insulated heat exchanger
Explanation:
A heat exchanger can be regarded as a system that bring about transfer heat between two or more than two fluids. It can function in cooling process and heating processes, the fluids involves in this process can have a solid wall to separate them so as to prevent mixing, direct contact could also be utilized. The mechanism is making hot gas jets which could fire upward over a glowing water that is passing through pipes, as water moves along the pipe, heat energy is been absorbed and there is heating up i.e heat is transferred. One is cooked the other is heated up. It is very essential to insulate the whole steam system along with heat exchangers so that energy could be saved and the temperature of the surface would be at safe-to-touch range and also steam quality could be maintained. The types of heat exchanger we have are;
✓Shell and tube heat exchangers.
✓Condensers, evaporators, and boilers
✓Double pipe heat exchangers.
✓Plate heat exchangers.
It should be noted Heat exchangers are devices where two moving fluid streams exchange heat (thermal energy) without mixing together
CsCl, when dissolved in water, produces the solution with a ph closest to 7.00.
<h3>What is pH?</h3>
In chemistry, pH, historically denoting "potential of hydrogen" (or "power of hydrogen"), is a scale used to specify the acidity or basicity of an aqueous solution.
Acidic solutions (solutions with higher concentrations of H+ ions) are measured to have lower pH values than basic or alkaline solutions.
The pH scale is logarithmic and inversely indicates the concentration of hydrogen ions in the solution.
Solutions with a pH less than 7 are acidic, and solutions with a pH greater than 7 are basic.
Solutions with a pH of 7 at this temperature are neutral (e.g. pure water).
The neutral value of the pH depends on the temperature – being lower than 7 if the temperature increases above 25 °C.
The pH value can be less than 0 for very concentrated strong acids, or greater than 14 for very concentrated strong bases.
