Consider a pipe that branches out into two parallel pipes and then rejoins at a junction downstream. the two parallel pipes have the same lengths and friction factors. the diameters of the pipes are 2 cm and 4 cm. if the flow rate in one pipe (2 cm diameter) is 10 l/min, the flow rate in the other pipe is :
a. 10 l/min
b. 3.3 l/min
c. 100 l/min
d. 40l/min
e. 56.6 l/min

Different types of steels contain different elements that alter the characteristics of the steel. for each of the following elements, explain what the element does when alloyed with steel.

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
