In today's engineering environment "scales" (the triangular plastic or wood instruments) are rarely used. However setting proper units of measurement and plotting to scale has not changed since computer aided drafting has come on the scene.

An incompressible fluid flows along a 0.20-m-diameter pipe with a uniform velocity of 3 m/s. If the pressure drop between the upstream and downstream sections of the pipe is 20 kPa, determine the power transferred to the fluid due to fluid normal

Air is compressed in the compressor of a turbojet engine. Air enters the compressor at 270 K and 58 kPa and exits the compressor at 465 K and 350 kPa. Take the average specific heat at constant pressure (cp, avg) of air as 1.015 kJ / kg.

A digital-to-analog converter uses a reference voltage of 120 V dc and has eight binary digit precision. In one of the sampling instants, the data contained in the binary register = 01010101.
