Acomposite wall is made of two layers of 0.3 m and 0.15 m thickness with surfaces held at 600°c and 20°c respectively. if the conductivities are 20 and 50 w/mk, determine the heat conducted. in order to restrict the heat loss to 5 kw/m2 another layer of 0.15 m thickness is proposed. determine the thermal conductivity of the material required

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

Fluids at rest possess no flow energy. a)- true b)- false

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.
