The figure below shows a horizontal pipe with a varying cross section. A liquid with a density of 1.65 g/cm flows from left to right in the pipe, from larger to smaller cross section. The left side's cross-sectional area is 10.0 cm, and while in this side, the speed of the liquid is 2.50 m/s, and the pressure is 1.20 x 105 Pa. The right side's cross sectional area is 3.50 cm? (a) What is the speed (in m/s) of...

Problem 3: Ordinary Differential Equations A straight fin of uniform rectangular cross section (0.5 mm x 100 mm) with a length (L) of 5 cm is attached to a base surface of temperature 110°C (T). The surface of the fin is exposed to a cooling fluid at 20°C (T) with a convection heat transfer coefficient (h) of 15 W/(m²K). The conductivity (k) of the fin material is 400 W/(m.K). (a) Plot the temperature profile along the length of the fin,...
