You are heating airflow in a long, round tube. The tube is irradiated uniformly, on all sides, with a constant thermal heat flux q". Inside the tube, the air flows with a known heat flux mdot and constant, known properties. The tube has a length L and a diameter D. This is your baseline case. You then add a helical coil inside the tube that stirs up the airflow and doubles the value of h over the baseline case. a) How does the design change impact the temperature of the airflow? b) How does the design change impact the temperature of the tube wall

The round off errors when measuring the distance that a long jumper has jumped is uniformly...

The round off errors when measuring the distance that a long jumper has jumped is uniformly distributed between 0 and 5.4 mm. Round values to 4 decimal places when possible. a. The mean of this distribution is b. The standard deviation is c. The probability that the round off error for a jumper's distance is exactly 3.6 is P(x = 3.6) = d. The probability that the round off error for the distance that a long jumper has jumped is...

Steam in a heating system flows through tube whose outer diameter is 10 cm and whose walls are maintained at a temperature of 150°C. Circular aluminum alloy 2024-T6 fins (k = 186 W/m · °C) of outer diameter 15 cm and constant thickness 2 mm are attached to the tube. Heat is transferred to the surrounding air at T∞ = 25°C, with a heat transfer coefficient of 50 W/m2 C . If the total tube length is 5 m and...

An electrical resistance heater embedded in thin walled tube provides 71 kW of uniform heating to increase the water temperature from 25°C to 75°C. Water enters the circular section of diameter 101 in cm, at a velocity 101 in cm/s. Heat loss to the surroundings is perfectly stopped by an insulation on the outer surface of the heater hence, all the heat dissipated by the heater is transferred to the flowing water in the tube. By analyzing the internal flow...

You have a column of air 1.2 m long. The hard bottom of the tube forces a node there and the open end at the top of the tube forces an antinode there. Sound waves from a 1024 Hz tuning fork are sent down the column. Compute the wavelengths and frequencies for the first three allowed harmonics within the column.

A Geiger tube consists of two elements, a long metal cylindrical shell and a long straight metal wire running down its central axis. Model the tube as if both the wire and cylinder are infinitely long. The central wire is positively charged and the outer cylinder is negatively charged. The potential difference between the wire and the cylinder is 1.10 kV. Suppose the cylinder in the Geiger tube has an inside diameter of 3.64 cm and the wire has a...

A speaker is placed at the opening of a long horizontal tube. The speaker oscillates at a frequency of f creating a wave that moves down the tube. The wave moves through the tube at a speed of v=330 m/s. At time t= 0s an air molecule at x=1m is at the maximum displacement of 5 nm. At the same time another molecule at x=3.7m has a displacement of 3.5nm. What is the wave function of the sound?

Airflow through a long, 0.15-m-square air conditioning duct maintains the outer duct surface temperature at 10°C. If the horizontal duct is uninsulated and exposed to air at 35°C in the crawlspace beneath a home, what is the heat gain per unit length of the duct? Evaluate the properties of air at 300 K. For the sides of the duct, use the more accurate Churchill and Chu correlations for laminar flow on vertical plates. What is the Rayleigh number for free...

A cylindrical tube that is 2.20 m long and has a radius of 150 mm is filled with water. It is oriented with its long central axis vertical, and it is open to the air at the upper end. A hole 80.0 mm in radius is drilled in the bottom, and the water is allowed to drain out. When the water level is half the height of the tube, (a) what is the speed of the water exiting through the...
