The fast freight shipping company charges the following rates: weight of package rate per 500 miles shipped 2 pounds or less $1.10 over 2 pounds but not more than 6 pounds $2.20 over 6 pounds but not more than 10 pounds $3.70 over 10 pounds $3.80 the shipping charges per 500 miles are not prorated. for example, if a 2-pound package is shipped 550 miles, the charges would be $2.20. write a program that asks the user to enter the weight of a package and then displays the shipping charges

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?
