Problem 4 (10 points) A pipeline with two pumps (Pump A and Pump B) in series delivers water between two tanks with a total static head of 50 ft. The pipeline is 8 inches in diameter and 5000 ft in length, with a Darcy- Weisbach friction factor f = 0.025. The total minor head loss coefficient Ek 20. The characteristics of the two pumps are shown in the following table. Determine (a) the operating conditions of head and discharge, (b)...

Two identical pumps in parallel configuration will be used to draw water from Reservoir A (water elevation 772') up to Reservoir B (water elevation -878'). The pipe will be 4,860 long, 2' diameter, with a Hazen-Williams coefficient of 100. Assume minor losses are negligible. The pump performance curve from thee manufacturer for one of these pumps is shown below. Determine the operation point for the two pumps in parallel by plotting below. Single pump 600 S00 400 Hp [ft] 300...

Q1: A venture meter is fitted in a pipe of 30 cm diameter inclined at 40° to the horizontal to measure the flow rate of petrol having a specific gravity of 0.8. The ratio of areas of main pipe and throat is 5 and the throat is at 1 m from the inlet along its length. The difference in manometer head is 40 mm of mercury. Assuming the coefficient of discharge as 0.96. Calculate the discharge through the venture...

Q3 Water is pumped between two reservoirs in a pipeline with a system characteristics represented by H 15 +85. Note that H. and are the system head (in meters) and volume flow rate (in m3/s), respectively. Since the operating conditions for the piping system is beyond the limit of a single standard pump, two identical pumps are thus used. The characteristics of a single pump may be approximated by H, 20 10, 100v Air dipam antara dua takungan dalam saluran...

Problem 4 (50 points) Water is discharged from a reservoir at a rate of 18.103 m3/s using two horizontal cast iron pipes connected in series and a pump between them. The first pipe is 20 m long and has a 6-cm diameter, while the second pipe is 35 m long and has a 4-cm diameter. The water level in the reservoir is 30 m above the centerline of the pipe. The pipe entrance is sharp-edged. Losses...

a.When two resistors RA and RB are combined in series and connected to a battery it is observed that the ratio of the power dissipated in RA to that dissipated in RB is equal to 10. If this arrangement is dismantled and the same two resistors connected in parallel to the same battery, what is the ratio of the power dissipated in RA to that dissipated in RB in this new circuit? b.How much energy is converted by a 12...

Answer TRUE OR FALSE. CHAPTER 1 1. Two notable trends in tax revenue sources is that social security taxes have decreased gradually while corporate income taxes have increased gradually over the last fifty years. 2. If a progressive tax rate system is used, as a taxpayer's taxable income decreases, a progressively higher rate of tax is applied. 3. The marginal tax rate measures the tax rate applicable to the next dollar of income or deduction for a taxpayer. 4. All...
