Occasionally, users at BITS obtain incorrect results when they run queries that include built-in (aggregate, summary, or statistical) functions. The DBA told management that unrepeatable reads caused the problems. Use books, articles, and/or the Web to research the unrepeatable-read problem. Write a short report that explains the unrepeatable-read problem to management and use an example with your explanation. (Note: Unrepeatable reads also are called inconsistent retrievals, dirty reads, and inconsistent reads.) If you use information from the Web, use reputable sites. Do not plagiarize or copy from the Web.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
