An air flow process has a flow rate of 0.76kg/s. The power input is 30KW and the heat transfer out is 3KW. Determine the specific enthalpy change and state if it is gain or loss.

i will 10 upvotes plz do fast A liquid of specific gravity 0.88 and absolute viscosity 6.533 x 10^-4 Ns/m is flowing through a pipe of diameter 0.15 m at the rate of 60 litres per second. If the loss of head in 100 m length of pipe is 4.56 m. Determine whether the pipe is rough or smooth.

Sam’s Long Life 75-watt light bulbs are designed tohave a life of 1125 hours with tolerances of 210 hours.The process that makes light bulbs has a mean of 1050hours, with a standard deviation of 55 hours. Computethe process capability ratio and the process capabilityindex, and comment on the overall capability of theprocess.

Two machines are currently in use in a process at the Dennis Kira Mfg. Co. The standards for this process are LSL = 450" and USL= 454". Machine One is currently producing with mean = 451" and standard deviation .0004"," Machine Two is currently producing with mean .4515" and standard deviation .0003". Which machine has the higher capability index? Machine One has an index of 0.83 (round your response to two decimal places). Machine Two has an index of (round your response to two decimal places).

Southern Mills Company One of the stages in the process of making denim cloth at the Southern Mills Company is to spin cotton yarn onto spindles for subsequent use in the weaving process. Occasionally the yarn breaks during the spinning process, and an operator ties it back together. Some number of breaks is considered normal; however, too many breaks may mean that the yarn is of poor quality. In order to monitor this process, the quality-control manager randomly selects a spinning machine each hour and checks the number of breaks during a 15-minute period. Following is a summary of the observations for the past 20 hours. Construct a c-chart using 3 limits for this process and indicate if the process was out of control at any time. Number of Number of Sample Breaks Sample Breaks 1 3 11 2 12 4 3 4 13 6 1 14 7 5 5 15 8 6 3 16 6 7 2 17 5 8 4 18 7 19 8 10 2 20 6

3.  Meena Chavan Corp.’s computer chip production process yields DRAM chips with an average life of 1,800 hours and σ=100 hours. The tolerance upper and lower specification limits are 2,400 hours and 1,600 hours, respectively. Is this process capable of producing DRAM chips to specification?

Sam’s Long Life 60-watt light bulbs are designed to have a life of 1,350 hours with tolerance of ± 340 hours. A recent representative sample from the process that makes these light bulbs revealed a mean of 1,290 hours, with a standard deviation of 94 hours. Compute a. Compute the process capability ratio and the process capability index, and comment on the overall capability of the process b. Explain to what extent the process for producing Sam’s Long Life 60-watt light bulbs would have to be improved to achieve 4-sigma quality. c. show detail work

The specifications for a gasket that installs between two engine parts calls for a thickness of 6.0 mm ± .2 mm. The standard deviation of the process is estimated to be 0.05 mm. The process is known to operate at a mean thickness of 6.1 mm   What are the upper and lower specification limits for the gasket? What are the Cp and Cpk values for this process? Is this process capable of producing the desired part?
