Agricultural Engineering (AG) 2007

A heater is placed in front of a continuous countercurrent dryer. Air at 40 °C and 70% RH is fed into the heater from which the air exits at 65 °C. If saturation vapour pressure at 40 °C and 65 °C are 0.074 bar and 0.250 bar respectively, then relative humidity of the air coming out of the heater and entering the dryer is

Convective heat transfer coefficient outside an ice cream block is 10 W m⁻² K⁻¹. Thermal conductivity of frozen ice cream is 0.3 W m⁻¹ K⁻¹. Convection takes place across a layer of 10 mm of air for 5 minutes. If the density and the specific heat capacity of ice cream are respectively 600 kg m⁻³ and 2.5 kJ kg⁻¹ K⁻¹, then 0.33 is

Milk is agitated in a tank with a rotating impeller. For this system: Let \(X = \frac{P}{\rho N^3 D^5}\), \(Y = \frac{D^2 N \rho}{\mu}\), \(Z = \frac{D N^2}{g}\) where, P = power imparted by the impeller to the fluid, N = rate of rotation of the impeller, D = impeller diameter, g = acceleration due to gravity, \(\rho\) = fluid density, and \(\mu\) = fluid viscosity. The X , Y , Z are

Milk enters into the heating section of a high temperature short time (HTST) pasteurization plant at a temperature of \(45^{\circ}\text{C}\) and leaves at \(72^{\circ}\text{C}\). Hot water at temperature of \(95^{\circ}\text{C}\) enters counter-currently into the heat exchanger and leaves at \(77^{\circ}\text{C}\). The effectiveness of the heat exchanger is
