Assume a 15 cm diameter wafer has a cost of 12, contains 84 dies, and has 0.020 defects/cm2 . Assume a 20 cm diameter wafer has a cost of 15, contains 100 dies, and has 0.031 defects/cm2. Find the yield for both wafers. Find the cost per die for both wafers. If the number of dies per wafer is increased by 10% and the defects per area unit increases by 15%, fi nd the die area and yield

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

At 12 noon, the count in a bacteria culture was 400; at 4: 00 pm the count was 1200 let p(t) denote the bacteria cou population growth law. find: (a) an expression for the bacteria count at any time t (b) the bacteria count at 10 am. (c) the time required for the bacteria count to reach 1800.
