Whether a part is forged or cast and the features should be investigated to arrive at a conclusion.

Expert Solution & Answer

Explanation of Solution

In manufacturing industries, the forging is one of the oldest manufacturing processes. It is a process in which material is converted into the finished product through heating, cooling, and hammering process. Some forging process are cold forging, die forging, and warm forging.

Casting is also one of the oldest manufacturing processes in which the molten raw material is shaped into a desired finished product with the use of molds. Some types of casting process are sand casting, die casting, centrifugal casting, and many more. Similar parts are prepared by forging process and casting process.

Some parameters such as temperature, toughness, tensile strength, hardness, microstructure, and many more are used to found whether the part is forged or cast. The cast and forged parts have different temperatures. The tensile test is done to investigate the toughness of the part because the forged part has higher toughness. In forging, there is plastic deformation take place; hence the forged parts are smaller grain size compared to the casting process. The main investigation is roughness and characteristics of the surface. The forged product is nearly always heavier compared to the cast product.

! Required information A one-shell-pass and eight-tube-passes heat exchanger is used to heat glycerin (cp=0.60 Btu/lbm.°F) from 80°F to 140°F by hot water (Cp = 1.0 Btu/lbm-°F) that enters the thin-walled 0.5-in-diameter tubes at 175°F and leaves at 120°F. The total length of the tubes in the heat exchanger is 400 ft. The convection heat transfer coefficient is 4 Btu/h-ft²°F on the glycerin (shell) side and 70 Btu/h-ft²°F on the water (tube) side. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Determine the rate of heat transfer in the heat exchanger before any fouling occurs.

! Required information Air at 25°C (cp=1006 J/kg.K) is to be heated to 58°C by hot oil at 80°C (cp = 2150 J/kg.K) in a cross-flow heat exchanger with air mixed and oil unmixed. The product of heat transfer surface area and the overall heat transfer coefficient is 750 W/K and the mass flow rate of air is twice that of oil. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Air Oil 80°C Determine the effectiveness of the heat exchanger.

In an industrial facility, a counter-flow double-pipe heat exchanger uses superheated steam at a temperature of 155°C to heat feed water at 30°C. The superheated steam experiences a temperature drop of 70°C as it exits the heat exchanger. The water to be heated flows through the heat exchanger tube of negligible thickness at a constant rate of 3.47 kg/s. The convective heat transfer coefficient on the superheated steam and water side is 850 W/m²K and 1250 W/m²K, respectively. To account for the fouling due to chemical impurities that might be present in the feed water, assume a fouling factor of 0.00015 m²-K/W for the water side. The specific heat of water is determined at an average temperature of (30 +70)°C/2 = 50°C and is taken to be J/kg.K. Cp= 4181 Water Steam What would be the required heat exchanger area in case of parallel-flow arrangement? The required heat exchanger area in case of parallel-flow arrangement is 1m².
