At a point in a circular duct with inner diameter of 0.200 m, the flow is fully developed and the air flow average velocity is 10.0 m/s with a mean temperature of 20.0° C. At a point exactly 5.00 m downstream, the mean temperature is 30.0° C. It is known that the wall temperature of the duct was held at a constant temperature between these two points. Find this wall temperature.

Question 1 a) A cylindrical feedstock of length = 35.4 cm and diameter = 10 cm is subjected to turning using a high speed steel tool. For this tool, n and C values in the Taylor tool life equation are 0.125 and 70 m/min, respectively. The cost for hiring an operator and using the machine tool are $82 per hour. The tooling cost per edge of cutting is $5. Loading and unloading the part on to the machine takes about...

Air enters a horizontal, constant-diameter heating duct operating at steady state at 280 K, 1 bar,...

Air enters a horizontal, constant-diameter heating duct operating at steady state at 280 K, 1 bar, with a volumetric flow rate of 0.25 m3/s, and exits at 325 K, 0.95 bar. The flow area is 0.05 m2. Assuming the ideal gas model with k = 1.4 for the air, determine: (a) the mass flow rate, in kg/s, (b) the velocity at the inlet and exit, each in m/s, and (c) the rate of heat transfer to the air, in kW

Air flows through a constant area duct. The pressure and temperature of the air at the...

Air flows through a constant area duct. The pressure and temperature of the air at the inlet to the duct are P1 = 100 kPa absolute, and T1 = 298 K, respectively. Inlet Mach number is M1 = 0.1. Heat is transferred to the air as it flows through the duct and as a result the Mach number at the exit increases. Write a Matlab code and plot the following: a) Find the pressure and temperature at the exit, while...

Air flows through a 0.25-m-diameter duct. At the inlet the velocity is 300 m/s, and the stagnation temperature is 90°C. If the Mach number at the exit is 0.3, determine the direction and the rate of heat transfer. For the same conditions at the inlet, determine the amount of heat that must be transferred to the system if the flow is to be sonic at the exit of the duct.
