(b) Use the following data to determine if flow is laminar or turbulent: Q = 12 bbl/min., Pipe I. D. = 6.0 inch, oil API = 34, viscosity = 5.0 c. P.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
