Abstract

In heat exchanger analysis using the Earth Air Heat Exchanger method, the overall heat transfer coefficient is known. This tool uses tubes in its design. The weakness of tube and plate type heat exchangers is the relatively low heat transfer coefficient, which can only reach a maximum of 60%. Therefore, a method to improve the heat transfer efficiency is using a fin. The purpose of this study is to calculate and compare the effectiveness (ε) value of experimental and theoretical of the Earth Air Heat Exchanger, as well as to find out the value of the coefficient of performance. The result showed that the average COP value of the experimental result is 0.63 at a speed of 1 m / s, 0.54 at the speed of 2 m / s, and 0.75 at the speed of 3 m / s, while theoretically is 0 , 73 at 1 m / s, 0.57 at 2 m / s, and 0.80 at 3m / s. For the value of the average effectiveness of the experimental results obtained 0.85 at the speed of 1 m / s, 0.93 at the speed of 2 m / s, and 0.89 at the speed of 3 m / s, while the theoretical result is 0.995 at the speed of 1 m / s, 0.997 at 2 m / s, and 0.998 at 3 m / s.

Abstract

The Markov chain hypothesis is the hypothesis discussed in stochastic interactions, and has several applications. This strategy is always coordinated with future situations whose whereabouts cannot be known with certainty, so the community tries to carry out exercises with future directions full of vulnerabilities. Hypotheses are numerical ways of dealing with competitive planning situations and the struggles between different interests. This hypothesis is designed to examine the dynamic cycle of various serious states and includes at least two interests. In this situation, the information obtained from the voting results is then assessed for its legitimacy and quality by using the SPSS program. The consequence of counting with Markov chain's S Noodle items reduces the share of the entire industry by 5.8%, while the fun noodle items expands a portion of the entire industry by 41%, the side effect of the game hypothesis being specific. namely X1 with probability 0.5, X2 with probability 0.5 and X3 with probability 3.16. Meanwhile, to limit misfortune, Indomie consolidates three systems, namely Y1 with likelihood - 0.1, Y2 with likelihood 0.5 and Y3 with likelihood 1.
