Consider a MOSFET with the oxide thickness of 4.5 nm. The oxide layer dielectric constant is 3.9. The gate length is L= 1.2 um; the gate width is W= 12 um. The electron mobility in the channel is 240 cm^2/Vs. The MOSFET threshold voltage is 0.6 V. The gate bias is VGS = 1.2 V. Velocity saturation effects in the MOSFET can be ignored.
(a) At what drain-sourse voltage the drain current saturates ? (Unit: V)
(b) Find the MOSFET saturation current, Isat. (Unit: uA)

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.

You are making beer. the first step is filling the glass carboy with the liquid wort. the internal diameter of the carboy is 15 in., and you wish to fill it up to a depth of 2 ft. if your wort is drawn from the kettle using a siphon process that flows at 3 gpm, how long will it take to fill?
