Start by checking your Reynolds number (Re) at the end of the
plate, where it will be at a maximum. This will determine if your
boundary layer is simply laminar along the length of the plate or
if it becomes turbulent (the "mixed BL" condition). Once you know
the conditions of the flow, you can solve for the velocity BL
thickness directly with an equation from the list of external flow
correlations (posted). Your properties should be looked up at...

Please make the hand writing legible. Thanks
Consider the situation depicted below, in which an incompressible fluid flows over a flat surface of solid. Upstream of the surface, the fluid has velocity U and uniform temperature To. As the fluid is viscous, both a momentum boundary layer, and a thermal boundary layer form, and heat is transferred to the solid surface. A convective coefficient h can be used to describe the dimensional heat transfer rate to the solid, and is...

1. You have a sheet of carbon steel with a thickness of 1 mm, a length of 300 mm, and width of 150 mm. You are testing it in a furnace that is flowing hot air over the sheet at 3 m/s at T 1 300 K along the length of the metal. The carbon steel is initially at 300k and has the following properties p 7850 R/ C 430 //kok, and R, 1490 W/mK. The carbon steel is sitting...

1a(30%). A refrigerant at an inlet temperature of -40 °C flows inside a copper pipe (ID= 3 cm, OD = 3.4 cm, circular cross-section). A 5 mm-thick insulation (k=0.04 W/mC) is added to the outside of the pipe, with a thermal contact resistance of R, "=0.9x10+m²K/W . For an ambient temperature of 20 °C, at a cross flow velocity of 1 m/s, find the heat gain for 1 m length of the pipe in W/m....

An insulating wall is composed of 10 cm of a material having an thermal conductivity of 5 W/m.K, and an unknown thickness of cork, which has a thermal conductivity of 0.045 W/m.K. How thick must the cork be if the heat losses through the wall are to be less than 10W/m2 when the inside temperature is 20degree C and it's -20degree C outside? Water flows through...
