Module 1: Worked out problems
A freezer compartment consists of a cubical cavity that is 2 m on a side. Assume the bottom
to be perfectly insulated. What is the minimum thickness of Styrofoam insulation
(k=0.030W/m.K) which must be applied to t
PROBLEM 1.1 KNOWN: Heat rate, q, through one-dimensional wall of area A, thickness L, thermal
conductivity k and inner temperature, T1. FIND: The outer temperature of the wall, T2. SCHEMATIC:
ASSUMPTIONS: (1) One-dimensional conduction in the x-direction,
Motion and Dynamics of Fluids
In this chapter we develop the fundamental laws of Conservation of Matter
and Newton's Second Law in differential form. First a relation is obtained
relating the time rate of change of a property of a moving p

a) xx = 1000 psi, yy = 0 psi, zz = 0 psi, xy = 500 psi, yz = 0 psi, zx = 0 psi
(3 5 = 15)
KNOWN: Width, input power and efficiency of a transmission. Temperature and convection
coefficient associated with air flow over the casing.
FIND: Surface temperature of casing.
