Consider fully developed axisymmetric Poiseuille flowâ€”flow in a round pipe of radius R (diameter D = 2R),with a forced pressure gradient dP/dx driving the flow as illustrated in Fig. P4â€“90. (dP/dx is constant and negative.)The flow is steady, incompressible, and axisymmetric about the x-axis. The velocity components are given by .... Read More

A 75-hp (shaft output) motor that has an efficiency of 91.0 percent is worn out and is to be replaced by a high efficiency motor that has an efficiency of 95.4 percent. The motor operates 4368 hours a year at a load factor of 0.75. Taking the cost of electricity to be $0.08/kWh, determine the amount of energy and money saved as a result of installing the high-efficiency motor instead of the standard motor. Also, determine the simple payback period if the purchase prices of the standard and .... Read More

Two aqueous sulfuric acid solutions containing 20.0 wt% H2SO4 (SG = 1.139) and 60.0 wt% H2SO4 (SG = 1.498) are mixed to form a 4.00 molar solution (SG = 1.213).(a) Calculate the mass fraction of sulfuric acid in the product solution.(b) Taking 100 kg of the 20% feed solution as a basis, draw and label a flowchart of this process, labeling both masses and volumes, and do the degree-of-freedom analysis. Calculate the feed ratio (liters 20% solution/liter 60% solution).(c) What feed rate of .... Read More

A natural gasâ€“fired furnace in a textile plant is used to provide steam at 130Â°C. At times of high demand, the furnace supplies heat to the steam at a rate of 30 MJ/s. The plant also uses up to 6 MW of electrical power purchased from the local power company. The plant management is considering converting the existing process plant into a cogeneration plant to meet both their process-heat and power requirements. Your job is to come up with some designs. Designs based on a gas turbine .... Read More
