A process fluid having a specific heat of 3500 J/kg?K and flowing at 2 kg/s is to be cooled from 80 °C to 40 °C with chilled water, which is supplied at a temperature of 15 °C and a flow rate of 2.5 kg/s. Assuming an overall heat transfer coefficient of 2000 W/m2?K, calculate the required heat transfer areas for the following exchanger configurations: (a) Parallel flow; (b) Counter flow; (c) a 1-2 shell and tube exchanger with the water on the shell side, (d) a 2-4 shell and tube exchanger with water on the shell side.

The fluid in a heat exchanger in a process plant needs to be warmed up prior to having process startup. The shell side of the heat exchanger contains the process fluid (water) while the tube side is supplied with steam at 150°C to facilitate the heating. Assume the exterior is well insulated such that heat losses are negligible. a) Derive the ODE and analytically solve for the function that describes the temperature of the fluid in the heat exchanger with...

A sugar solution (? = 1080 kg/m3, cp = 3601 J/kg ? K, kf = 0.5764 W/m ? K, ? = 1.3 × 10–3 N ? s/m2) flows at rate of 60,000 kg/hr and is to be heated from 25°C to 50°C. Water at 95°C is available at a flow rate of 75,000 kg/hr (cp = 4004 J/kg ? K). It is proposed to use a one shell pass and two tubes pass shell-and-tube heat exchanger containing 3/4 in. OD,...

Water at a flow rate of 60 kg/s enters the shell-side of a baffled shell-and-tube heat exchanger at 35 °C and leaves at 25 °C. The heat will be transferred to 150 kg/s of raw water coming from a supply at 15 °C. You are requested to design the heat exchanger for this purpose. A single shell and single tube pass is preferable. The tube diameter is ¾ in. (19 mm outer diameter with 16 mm inner diameter) and tubes...

Saturated water vapor leaves a steam turbine at a flow rate of 1.47 kg/s and a pressure of 0.51 bar. The vapor is to be completely condensed to saturated liquid in a shell-and-tube heat exchanger that uses city water as the cold fluid. The water enters the thin-walled tubes at 17oC and is to leave at 57.6 oC. Assuming an overall heat transfer coefficient of 2000 W/m2K, determine the required heat exchanger surface area and the water flow rate. cp,c...

A 1-shell-2-tube pass heat exchanger is made of a steel alloy (thermal conductivity 45.4 W/(m K). It is used to cool distilled water from 34oC to 29oC using water which flows inside tubes with an outer diameter of 19 mm and an inner diameter of 16 mm. The number of tubes in the shell is 160 (80 per pass). The mass flow rate of distilled water in the shell is 76180 kg/h. The cold water enters the heat exchanger at...

A complex medium needs to be heated from 15°C to 37°C prior to use in mammalian cell culture. You are responsible for deciding the type of heat exchanger to adopt to achieve this heating. You are considering using a doublepipe heat exchanger with either co-current or counter-current flow. The medium flows through the inner tube and hot water enters the outer annulus at 80°C. You are given the following data: Cell culture medium: Mass flowrate = 2 kg s-1 Specific...

Question 2. Answer all parts of this question a) A shell and tube heat exchanger is to heat 10,000 kg h–1 of water from 16 to 84°C using hot oil entering at 160°C and leaving at 92°C. The oil will flow through the shell of the heat exchanger. The water will flow through 11 brass tubes of 22.9 mm inside diameter and 25.4 mm outside diameter, with thermal conductivity 137 W m–1 K–1, with each tube making two passes through...

The condenser of a large steam power plant is a heat exchanger in which steam is condensed to liquid water. Assume the condenser to be a parallel flow shell-and-tube heat exchanger consisting of a single shell and 10,000 tubes, each executing two passes. The tubes are of thin wall construction with D = 30 mm and the steam condenses on their outer surface. The heat transfer rate that must be effected by the exchanger is Q = 2 × 10^9...

A heat recovery unit in a factory uses a shell-in-tube counter flow type unit to recover heat from a flow of hot fluid to preheat water for the factory. The hot fluid enters at 88°C and a flow rate of 25 kg/minute, and exits at 55°C. The cold water will enter the heat exchanger at 15°C and exit at 55°C. Take cHot-fluid = 3000 J/kg.K, cwater = 4200 J/kg.K. PART (b) An air to water heat exchanger with an effectiveness...
