Air enters a pipe at 25 Celsius, 100 kPa at a flow rate of 36 m3/hr. A heater on the outside of the pipe draws 8 amps at a voltage of 120 V. All the heat from the heater is transferred to the air (well insulated and wall t is small). Assuming that the air behaves as an ideal gas and ignoring KE and PE, (a) determine the mass flow rate of the air in kg/s and (b) the temperature of the air at the exit.
consider a supersonic flow of free stream velocity of mach 3 is flowing over a diamond-wedge airfoil with half angle
We are asked to measure value and voltage across resistor in DC circuit. Explain why - statistical analysis of resistance measurements in different configurations; building series/parallel circuits to compare experimental to theoretical values to ana..
a hot-wire anemometer is a temperature-based instrument for measuring velocities in a flowing gas. the key component of
the sphere of mass m1 travels with an initial velocity v1 directed as shown and strikes the sphere of mass m2. for a
How often would the sample have to be taken - If the objective was to determine the average value of the material in the bunker, how could this be done by making one measurement?
A pin-connected structure consists of a rigid beam ABCD and two supporting bars. Bar (1) is an aluminium alloy [E = 70 GPa] with a cross-sectional area of A1 = 2,400 mm2. Bar (2) is a bronze alloy [E = 100 GPa] with a cross-sectional area of A2 = 6,0..
A metal is being cast into a cylinder which is 10 cm in diameter and 20 cm tall. The mold is bottom-gated (see class notes for geometry)

The cost of operating a large ship (CO) varies as the square of its velocity (v); specifically, CO = knv2 , where n is the trip length in miles and k is a constant of proportionality. It is known that at 12 miles/hour, the average cost of operation i..
Assume that the center of masses of the upper arm and the forearm acts in the geometric center of the respective body segment, and the center of mass of the hand acts at the same location that the cable is in the hand (given below). If the person is ..
