Derive the expressions for maximum rate of climb, (?? ?? ?
)?????? and the velocity at maximum rate of climb, ??(?? /C )??????
for propeller-driven and jet-propelled A/C.
What is the maximum angle of climb (steady velocity climb) for a
turbojet powered aircraft with an (L?D)max equal to 10.5 and a
gross weight of 8000 lb. if it is producing a thrust of 2000 lb.?
If the aircraft using the same available thrust, wishes to
establish a rate of climb equal to 1800fpm, what airspeed will it
need to establish? (Assume the required thrust equals
764pounds)
Derive velocity distribution, maximum velocity, average
velocity, and force in z-direction for the following flow
conditions, and state your assumptions
Flow of Newtonian fluid in the form of film over flat plate due
to gravity, if kept vertical.
Flow of Newtonian fluid in the form of film over flat plate due to
pressure force, if kept horizontal
Flow of non-Newtonian fluid in the form of film over flat plate due
to gravity, if kept vertical.
Flow of non-Newtonian fluid in...
Use the following data to determine the maximum rate at which a
standard man can climb a mountain: Blood contains 15.9 wt%
hemoglobin (with molecular weight 65,000 g/mol). Each hemoglobin
molecule can carry four oxygen molecules. The heart pumps 107
cm3/s blood of density 1.06 g/cm3. Each
oxygen molecule can oxidize one sugar unit (the chemical formula
per sugar unit is CH2O, which is an organic alcohol
group) to CO2 and H2O; the oxidation of 1 g
sugar yields about...

Derive expressions for constant rate filtration and
constant pressure difference filtration and explain clearly the
difference between these filtration techniques.
1. Derive expressions for the differential and common mode gains
of the amplifier and thence derive the common mode rejection ratio
(CMRR). Explain the design steps necessary to achieve a high
CMRR.
2. If the differential gain of the first stage of the amplifier
is 100 and the -& resistor values associated with the second
stage are R1= 15k, R2= 10.5k, R3= 200k and R4= 101k, calculate the
CMRR of the whole system.
3. Explain the operation of a Lock...
The NASA “Vomit Comet” is in a maximum performance 55 degree
pitch angle climb in preparation
to conduct weightless operations at high altitude. Assume that the
engines produce forward thrust
in-line with the longitudinal axis of the plane.
a. At this pitch angle what % of the engine thrust is in the
vertical direction?
b. What % of the engine thrust is in the horizontal direction?
(Keep in mind that, due to the
pythagorean theorem, your two percentages may add...

In the following you will derive expressions for the energy
stored in magnetic and electric
fields. Although you will start with specfic situations, the
expressions you derive will be general.
(a) (7 points) Find an expression for the energy per unit
volume contained inside of a parallel plate
capacitor in terms of the electric field between the plates.
This is a general equation and works for
any electric field.
(b) (7 points) Find an expression for the...
