What is commercial refrigeration system? Using this principle, commercial refrigeration systems utilize a refrigerant solution to transfer heat from the food inside the refrigeration unit’s storage area to the refrigerant. Refrigerant solutions obey a second physical principle, which states that gases cool as they expand and heat up as they are compressed. What is marine […]
What does an open feedwater heater do?
What does an open feedwater heater do? An open feedwater heater is basically a mixing chamber, where the steam extracted from the turbine mixes with the water exiting the pump. In an ideal condition, the water leaves the heater as a saturated liquid at the heater pressure. What is the major purpose of using feedwater […]
How do you calculate the compression ratio of a diesel engine?
How do you calculate the compression ratio of a diesel engine? Plug your numbers into the formula CR = (Vsw + Vcl) / Vcl. Now that you know the swept volume and clearance volume, simply insert those numbers into the formula and solve it. Add the swept volume and cylinder volume together first. Then, divide […]

What is the importance of dimensional analysis?
What is the importance of dimensional analysis? Dimensional analysis can be used as a tool to construct equations that relate non-associated physico-chemical properties. The equations may reveal hitherto unknown or overlooked properties of matter, in the form of left-over dimensions — dimensional adjusters — that can then be assigned physical significance. What are the applications […]
