15 5 Determine the free air volume flow rate required for a single acting cylinder if the system gauge pressure is 5 bar, the piston has a diameter of 80 mm, the stroke length is 400 mm and the cylinder completes 10 strokes per minute. Take the ambient pressure to be 101 kPa. Student answer

A manual assembly line is being designed for a product with annual demand = 100,000 units. The line will operate 50 wks/year, 5 shifts/wk, and 7.5 hr/shift. Work units will be attached to a continuously moving conveyor. Work content time = 42.0 min. Assume line efficiency E = 0.97, balancing efficiency Eb = 0.92, and repositioning time Tr = 6 sec. Determine: (a) hourly production rate to meet demand, (b) number of workers required.

100 mL of a 0.1 M solution is titrated with 50 mL of 0.1 M NaOH. The new solution has a pH of 4.75. Upon addition of 10 mL more of 0.1 M NaOH, the pH of the solution is 5.00. a. What is the identity of the original 100 mL 0.1 M solution? HCI O NaOH O acetic acid water KOH

Suppose an average of 240 trucks arrive each​ day, there are fourfour wellhead​ pumps, and each pump can serve an average of 3 trucks per hour. What is the probability that exactly 10trucks will arrive between 2​:00 p.m. and 4​:00 p.m. on any given​ day? How likely is it that once a truck is in position at a​ wellhead, the filling time will be less than 15 minutes? The probablity that 1010 trucks will arrive between 22​:00 p.m. and 44​:00 p.m. is .58​%. The probability that the filling time for the truck being served will be less than 15 minutes is ___%

A belt runs on a wheel of radius R = 0.40 m. During the time it takes the wheel to decelerate uniformly to rest from an initial angular speed of 10.0 rad/s, a length L = 0.82 m of the belt passes over the wheel without slipping. Find the (net linear) acceleration at point P when the wheel is spinning at 5.0 rad/s.

At -8.64 °C the concentration equilibrium constant K = 7.7 for a certain reaction. Here are some facts about the reaction: -1 • The initial rate of the reaction is 5.3 mol·L¯¹·s¯¹. . If the reaction is run at constant pressure, 132. kJ/mol of heat are absorbed. • The constant pressure molar heat capacity C = 2.97 J'mol K¹. Yes. Using these facts, can you calculate K at 16. °C? x10 O No. If you said yes, then enter your answer at right. Round it to 2 significant digits. If you said no, can you at least decide whether Kat 16. °C will be bigger or smaller than K at -8.64 °C? C Yes, and K will be bigger. Yes, and K will be smaller. No.

The figure below shows a 114-turn square coil rotating about a vertical axis at at -1,770 rev/min. The length of a side of the coil is 20.0 cm. The horizontal component of the Earth's magnetic field at the coil's location is equal to 2.00 x 10-5 T. 20.0 cm 20.0 cm (a) What is the magnitude of the maximum emf (in mV) induced in the coil by the Earth's magnetic field? mV (b) What is the orientation of the coil with respect to the magnetic field when the maximum emf occurs? O The plane of the coil is parallel to the magnetic field. The plane of the coil is perpendicular to the magnetic field. ○ The plane of the coil is oriented 45° with respect to the magnetic field.

3. Useful lives are equal to the study period At the Motorola plant in Mesa, Arizona, it is desired to determine whether oneinch-thick insulation or two-inch-thick insulation should be used to reduce heat loss from a long section of steam pipe. The heat loss from this pipe without any insulation would cost $2.00 per linear foot per year. The one-inch insulation will eliminate 88% of the heat loss and will cost $0.60 per foot. Two-inch insulation will eliminate 92% of the heat loss and will cost $1.10 per foot. The steam pipe is 1,000 feet in length and will last for10 years. MARR = 6% per year. Which insulation thickness should be recommended?
