The wing of an aircraft is approximately rectangular with a wingspan of 17.5m and a chord of 3m. the aircraft is flying at sea level with a velocity of 200 m/s. if the flow is completely laminar and incompressible, calculate the boundary layer thickness at the trailing edge and the total skin friction drag.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Manometers are good examples of measuring instruments, nowadays they are not as common as before. a)-capacitive probe gauges b)-gravitational gauges deformation ) gauges d)-digital gauges

Calculate the bore of a cylinder that has a stroke of 18 inches and an extension time of 6 seconds at a flow rate of 4 gal/min.
