A thin flat plate is installed in a water tunnel as a splitter. The plate is 0.3 m long and 1 m wide. The freestream speed is 1.6 m/s. Laminar boundary layers from on both sides of the plate. The boundary layer-velocity profile is approximated as parabolic. Determine the total viscous drag force on the plate assuming that pressure drag is negligible.
An air heater may be fabricated by coiling Nichrome wire and passing air in cross flow over the wire. Consider a heater fabricated from wire of diameter D=1 mm, L= 2m, electrical resistivity rho=10^-6 ohms, thermal conductivity k=25W/mK, and emiss..
a 50 cm long 800 w electric resistance heating element with diameter .5 cm and surface temperature 120c is immersed in 60 kg of water temperature to 80c. also determine the convection heat transfer coefficients at the beginning and at the end of t..
The catapult is used to launch a ball such that it strikes the wall of the building at the maximum height of its trajectory. If it takes 1.5 s to travel from A to B, determine the velocity vA at which it was launched, the angle of release q, and t..
Identify the mass properties that would be used to determine an appropriate size box to package 60 ABS Plastic (0.038 lb/in3) blanks and to ship them at $1.15 per pound.
the rigid gate oab shown in the figure below is hinged at o and rests against a rigid support at b. what minimum
A ball with a mass of 0.25 kg is thrown vertically upward with an initial velocity of 10 m/s. What is the velocity of the ball when it reaches the highest point?
the force exerted on the cue ball by the cue is horizontal. determine the value of h for which the ball rolls without
