Light oil at 75°f flows over a 22-ft-long flat plate with a free-stream velocity of 5 ft/s. take the critical reynolds number as recr = 5 × 105 and the density and kinematic viscosity of light oil at 75°f as rho = 55.3 lbm/ft3 and v = 7.751 × 10–3 ft2/s. determine the total drag force per unit width of the plate. (round the final answer to two decimal places.)

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

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length
