In business applications, you are often asked to compute the mean and standard deviation of data. The mean is simply the average of the numbers. The standard deviation is a statistic that tells you how tightly all the data are clustered around the mean in a set of data. Compute the standard deviation of numbers. Please use the following formula to compute the standard deviation of n numbers. m = ∑ x =1 = x1+x2+⋯+x o = √ ∑ (x − m) 2 =1 − 1 To compute the standard deviation using the above formula, you have to store the individual numbers using an array, so they can be used after the mean is obtained. Your program should contain the following methods: /** to compute the deviation of double values**/ public static double deviation(double[] x) /** to compute the mean of an array of double values**/ public static double mean(double[] x) write a test program that prompts the user to en

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Asteam turbine is supplied with steam at 28bar and 425c. a fraction of the steam is extracted at 1.2bar to heat the feed water in one open feed water heater. the rest of the steam expands in the low pressure stage of the turbine to 0.08bar. a)-sketch the regenerative rankine cycle with open feed water heater on the t-s diagram. b)-assuming isentropic expansion in both stages of the turbine, find the cycle efficiency. do not assume negligible pump work.
