In this paper. the analytical solution to the problem of heat transfer and fluid flow was obtained by using the quadruple Laplace transform method. Temperature distribution and fluid flow distribution were shown. temperature and fluid flow increase when the value of z increases. https://www.diegojavierfares.com/top-price-DC-Sports-B-Series-Ceramic-Coated-Header-94-01-Acura-Integra-flash-choice/
