Hot water at a constant volumetric flow rate of Fh and temperature Th(t) is mixed with cold water at a constant volumetric flow rate of Fc and a constant temperature of Tc. Both streams flow into a bathtub, but because of carelessness, the water is overflowing and keeping the bathtub full of water. The bathtub volume is V, and the heat loss can be ignored. Assuming the water in the bathtub is perfectly mixed and constant density and heat capacity, derive the differential equation relating the temperature in the bathtub, T(t), to the temperature of the hot water, Th(t).

The oil (poil = 56.8 lbm/ft³) forms into oil droplets that rise upward due to their lower specific gravity and are trapped by a baffle, creating an oil layer with a cross-sectional area, A, of 10 ft². Water (Pwater = 62.2 lbm/ft³) flows out of the device at a rate of 20 lbm/hr. The water level in the device remains constant, but the height, h, of the oil layer increases at the rate of 1 inch per day. What are the mass flow rates of oil and water into the device in lbm/hr? You may assume that the water and oil do not mix. water h oil layer oil droplets oil A = 10 ft² water baffle baffle HW Set 7 water

Control volume concept can be used to obtain forces in both internal and external flow. By drawing a control volume around a region of fluid to expose the stresses acting on the boundaries and applying the conservation of mass and conservation of momentum in integral form, the net forces acting on the fluid and hence the reaction forces acting on the solid boundary can be calculated. The advantages of this approach over differential approach are: (i) It is an easy way to obtain net forces. (ii) It gives a detailed understanding of how these forces are generated. (iii) It is commonly used in engineering practice to obtain reaction forces on pump, turbine, elbow, etc. for the design of anchoring fixtures/foundation. (A) (B) (C) (D) (i) and (ii) (i) and (iii) (ii) and (iii) All of the above
Your team is designing a chemical processing plant. You are the liquid handling and transportation specialist, and you need to transport a solvent (μ = 3.1 cP, ρ = 122k kg/m3) from a storage tank to a reaction vessel. Due to other equipment constraints, the fluid velocity must be 0.8 m/sec, and you must use stainless steel piping (ε = 0.00015 mm) with a total length (L) of 12 m. Determine the pipe inner diameter (ID) you will need to achieve a pressure drop of 0.3 kPa. Use the Moody chart.
