ENGINEERING
Determine the region of operation for a room-temperature silicon $npn$ transistor that has $\beta=100$ if a. $V_{CE}=10$ V and $I_B=20\ \mu$A; b. $I_C=I_B=0$; c. $V_{CE}=3$ V and $V_{BE}=0.4$ V; d. $I_C=1$ mA and $I_B=50\ \mu$ A.
ENGINEERING
You roll a pair of fair dice until you roll "doubles" (i.e., both dice are the same). What is the expected number, E[N], of rolls?
ENGINEERING
A jet of fresh water under pressure issues from the 3/4-in.-diameter fixed nozzle with a velocity v = 120 ft/sec and is diverted into the two equal streams. Neglect any energy loss in the streams and compute the force F required to hold the vane in place.
ENGINEERING
For an unsteady, compressible flow field that is two- dimensional in the. x- y plane and in which temperature and density variations are significant, how many unknowns are there? List the equations required to solve for these unknowns. ( Note: Assume other flow properties like viscosity. thermal conductivity, etc. can be treated as constants.)
