VI. Analisa DataDari data percobaan yang ditampilkandiatas,
terlihatkinerjadari heat exchanger shell and tube tipe BEU.
Terdapatpermasalahan yang ditemukanpada heat exchanger ini, yaitu
over design yang bernilainegatif (-3.66%) danbesarnya actual
overall coefficient heat transfer lebihrendahdibanding required
overall coefficient heat transfer (U = 129.01 W/m2-K; Ureq = 133.91
