1. For natural convection problems, if α is replaced by ν in the nondimensional scaling, derive the new non-dimensional form.
2. Calculate laminar flow and heat transfer from a hot cylinder at Re = 40 using the CBS flow code. Assume the buoyancy effect is negligible.
If a slider block C is fixed to the disk that has a constant counter clockwise angular velocity of 4 rad/sec, determine the angular velocity and angular acceleration of the slotted arm AB at the instant shown.
find the displacement function u(x,t). Both ends are fixed, P = 50 N, and the mass per unit length is 0.01 kg/m. With what frequency does the wire oscillate? Write the eigenvalue and eigenfunction for part (a).
A closed system consisting of 1 lb of a gas undergoes a process during which the relation between pressure and volume is pV^n = constant. The process begins with p1=20 lbf/in^2, V1=10ft^3 and ends with p2=100 lbf/in^2.
A person jumps off a diving board 4.0m above the water's surface into a deep pool. The person's downward motion stops 2.0m below the surface of the water. Estimate the average deceleration of the person while under the water.
The velocity of the airstream was measured using a thermistor- based anemometer, and thermocouples were used to determine the temperatures of the airstream and the test-plate.
an air conditioner operating at steady-state takes in moist air at 27 oc 1 bar and 70 relative humidity. the moist air
An A/D converter is to be supplied for an experimental transducer that has a dynamic range of 45 dB and a maximum voltage of 90 mV. Determine the number of bits for the converter to ensure a resolution of ±0.2 dB at the 0 dB condition.
5 bolts are made of low carbon steel with a yield point in shear of 19200 psi. the bolts are 38 inch in diameter and
Electrostatic forces. Two thin, segments, each 1 m long, are charged with line charge densities of 10 nC/m and -10 nC/m and are placed a distance 10 mm apart, parallel to each other. Calculate the total force one segment exerts on the other.
Determine the longitudinal normal strain ε at the top surface of the strip.
Derive analytical expressions for the helmoltz free energy fundamental relation of a single component ideal gas F(t, v, n) and for the Gibbs free energy fundamental relation of the same substance G(t,p,n)
