Suppose you wish to estimate a population mean correct to within 0.15 with a confidence level of .90. You do not know \sigma^2, but you know that the observations will range in value between 35 and 43. Complete parts a and b. a. Find the approximate sample size that will produce the desired accuracy of the estimate. You wish to be conservative to ensure that the sample size will be ample for achieving the desired accuracy of the estimate. (Hint: assume that the range of the observations will equal 4\sigma.) The approximate sample size is 4. (Round up to the nearest integer.)

(5 Marks) (c) A hot water supply (HWS) calorifier stores 600 litres of water at 65°C from feed water at 10°C with a regeneration of 1.5 hours. If the primary connection is supplied with steam at 3 bar absolute 0.9 dry, determine the mass flow of steam required, the size of steam connection and the actual steam velocity. Assume a maximum steam velocity of 10 m/s and that condensate leaves the primary exchanger at 130°C. Ignore the inefficiency of the heat exchanger. (10 Marks)
