An extruder barrel has a diameter of 5 in and a length of 12 ft. It screw has a channel depth of 0.3 in, and rotates at 50 rev/ min. The plastic melt has a velocity of ?100 ×10?^(-4) lb-sec/?in?^2 . The die characteristic is Q_x = 0.0015p where p is the head pressure in psi. Determine the flight angle that maximizes the flow rate Q_x and graph it.
Water enters a 2 meter diameter pipe at a temperature of 23 deg C. The water leaves the pipe at a temperature of 97 deg C The laminar flow rate is such that the Reynolds number is 800. What is the mass flow rate?

find the total heat loss per m length of the steam line. Find also the temperature at the interface of steam and insulation.
A bullet is fired horizontally into a wood block resting on a horizontal, frictionless surface. If the mass of the bullet is 0.02 Kg and the velocity is 600 m/s
Air enters a 0.6 m diameter fan at 16 deg C, 101 kPa, and is discharged at 18 deg C, 105 kPa, with a volumetric flow rate of 0.35 m^3/s.
The heating is to be done in a mixing tank by direct injection of the steam, all of which condenses. Determine the two inlet mass flows needed to meet the desired hot water flow rate.
Find the stoichiometric A/F ratio (by mass) for the combustion of benzene (C6H6). Compute the actual A/F ratio and do a wet and dry analysis of the products by volume at a mixture strength of 95%.
You have a 120 Ω quarter bridge 2 wire set up with Sg=2.10 and an unknown lead wire resistance. A 59880Ω calibration resistor is switched in parallel to the gage only and a recording instrument is set to give a -100 mm deflection for this calibrat..
