Assign deliverycost with the cost (in dollars) to deliver a piece of baggage weighing baggageweight. the baggage delivery service charges twenty dollars for the first 50 pounds and one dolllar for each additional pound. the baggage delivery service calculates delivery charge by rounding to the next pound. assume baggageweight is always greater than 50 pounds. ex: if baggageweight is 65.4 pounds, then the weight is rounded to 66 pounds and deliverycost is 20 + (16 * 1) = 36 dollars.

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
