of hydraulic bench. 8. Let the water flow through the system for a while. 9. Note down the reading on the differential pressure indicator. 10. Close the drain‚ use a stopwatch to time a certain amount of water flowing into the measuring tank and calculate the flow rate. 11. Once it is done‚ open the drain and let the water flow into the sump tank. 12. Change the flow rate of water by adjusting outlet control valve to get different differential pressure reading. 13. Again‚ take the differential pressure

For three heat exchanger will get Ce = 33‚844.86 The pump for service water will present 3 pumps. Due to the service water will apply in the process depend on the control system or the season change so the flow rate approximately to 150 L/sec. The Ce can calculate by use the data in SINNOTT book this Ce include the cooling water and pump that

permanganate standard and calculate the concentration of the ferrous solution. First‚ Mohr’s salt was mixed with H2SO4. Then‚ the solution was titrated until the end point was reached. The volumes were recorded‚ and used to calculate the molarity of the ferrous solution. The major findings in this lab were that titration in a redox reaction can be used to find the concentration of one solution if the other one is given. This lab’s significance is that it shows the proper way to calculate molarities using

With the help of following data‚ calculate National Income at factor cost. GNP = 5‚ 00‚000 Crs. Depreciation = 50‚000 Crs. Indirect taxes = 30‚000 Crs. Subsidies = 5‚000 Crs. Solution: NI at factor cost = GNP – Depreciation – Taxes + Subsidies. = 5‚ 00‚000- 50‚000 – 30‚000+5‚000 = 4‚ 25‚000 Crs. Calculate GNP and NNP from the following

1. Calculate real GDP for 2004 and 2005 using 2004 prices. To calculate the real GDP we use the constant price for 2004 which was $20. Real GDP (base year 2004) 2004 ($20 per CD x 100 CD’s) + ($110 per racquet x 200 racquets) = 24000 2005 ($20 per CD x 120 CD’s) + ($110 per racquet x 210 racquets) = 25500 By what percentage did real GDP grow? Because the Real GDP was $24000 in 2004 and $25500 in 2005‚ real GDP grew by ($25500 - $24000) / $24000 = 0.0625 or 6.25% 2. Calculate the

Keep in mind the following: 1) make sure to use the adjusted close prices to calculate returns (so that you won’t have large‚ spurious negative returns due to dividend payments or splits)‚ and 2) calculate log returns (so that you can aggregate daily returns to obtain holding period returns‚ if ever needed). In Excel‚ the function for mean and standard deviation are “= average (range)” and “stdev(range).” To calculate the correlation matrix‚ use “correlation” under “data analysis.” Please note
