Ahigh-tech company wants to have $2.5 billion available in 5 years to develop a new product. the company expects to invest uniformly increasing amounts of money each year to meet this goal. at the end of the first year, the company will deposit $50 million in an account that is expected to earn 10% annually. determine how much the uniformly increasing deposit must be each year thereafter to meet this goal.

Air inially occupying a volume of 1 m2 at 100 kpa, 27 c undergoes three internally reversible processes in series. process 1-2 compression to 500 kpa during which pv constant process 2-3 adiabatic expanslon to 100 kpa process 3-1: constant-pressure expansion to 100 kpa (a) calculate the change of entropy for each of the three processes. (b) calculate the heat and work involved in each process. (c) is this cycle a power cycle or refrigeration cycle?

Brief discuss how the presence of dislocations in crystal structures can be an advantage and a disadvantage to engineer and designers.

Afan that can provide air speeds up to 60 m/s is to be used in a low-speed wind tunnel with atmospheric air at 35 c. if one wishes to use the wind tunnel to study flat-plate boundary layer behavior up to reynolds numbes of re 10, what is the minimum plate length that should be used? at what distance from the leading edge would transition occur if the critical reynolds nurnber were rer,e = 5 × 105?
