Final answer:
To find the flow per hour, we determined the total non-working time, converted the working period into hours, and divided the total volume by the number of productive hours. The resulting flow rate does not match the provided options.
Step-by-step explanation:
To calculate the flow/hour, we first need to determine the total amount of non-working time during the shift to subtract from the 8 hours. A 7-minute stand-up, two 15-minute breaks, and a 15-minute stow down sum up to 52 minutes non-working time. Therefore, the total working time in minutes is 8 hours minus 52 minutes, which is 480 minutes - 52 minutes = 428 minutes. Next, we convert 428 minutes to hours by dividing by 60, yielding approximately 7.13 hours.
Finally, we use the formula Flow rate (in volume/hour) = Total volume / Total working hours to find the flow per hour. Thus, the flow/hour is calculated as 49,021 divided by 7.13, which equals approximately 6,877.84. This number does not match any of the provided options (A) 107 (B) 119 (C) 131 (D) 143, indicating there may be a discrepancy with the question or the provided options.
