The most common types of heat exchangers are parallel flow and counter flow. Since they are used in so many places, there are several types and arrangements in which an engineer designs a heat exchanger. This device has several applications ranging from the air conditioners in your room to the vehicle you drive, all the way to massive nuclear reactors and everything in between.
The heat exchanger is a device specifically designed to take advantage of the phenomenon for either heating or cooling processes. The equation is generally used to estimate heat transfer through walls, shells, and also heat exchangers. When you calculate heat transfer, you must have noticed the term for temperature difference in the equation along with heat transfer coefficient, mass flow rate, and the area. In expressions of the logarithm of a product and a number, we can calculate them by firstly moving the multiple from the left side of the expression and raising the exponent to the power of that multiple.You can use the LMTD calculator to determine the logarithmic mean temperature difference (LMTD) for a heat transfer process. \log_a (b) - \log_a (c) = \log_a (b \div c) A number times log expression Subtraction of two logs with the same base is done by dividing their exponents: \log_a (b) + \log_a (c) = \log_a (b \times c) Subtracting logarithms If we have two logs with the same base and we want to add them – multiply their exponents:
In other examples, we evaluate logarithms by expanding logarithms. So weve evaluated the logarithm by first condensing logarithms, then setting the condensed logarithm equal to x, then converting it to exponential form. Sometimes, if you see a logarithmic expression without a base, it means that the base is 10. Finally, we convert the logarithmic expression to exponential form, and we have 8x 64, so x 2. and answer (how many times we need to multiply the base to get the argument).base (a number that we multiply by the answer number).Logarithmic expressions does not have only one log property, but three specific properties you should know: So, the log is 3, and we write it down this way: \log_3 (27) = 3 For example, let’s look at the example below:ģ \times 3 \times 3 = 27 -> We need to multiply the number of 3 three times by itself to get 27. In algebra, you learn about logarithmic functions. However, everybody hears about this math concept in high school (algebra), if not even earlier. Thus, if you want to have basic math skills, you should definitely know them. In terms of math problems, logs are very useful in solving them. What is a logarithm?Ī logarithm is a math expression that tells us which power we need to raise a particular number, “a” to get a number “b”.
