In a canning industry, the total process time $ F_0 $ was calculated as 3 min. If each can contains 20 spores with decimal reduction time of 1.6 min, the probability of spoilage would be _________ $\text{ in 100 cans. (round off to the nearest integer)}$

Which among the following statements are true with respect to protein denaturation?

Identify the correct pair(s) of milling equipment and the grain for which it is used.

In a dairy processing plant, milk enters a 30 m long and 2 cm diameter tube at 60°C and leaves at 57°C. The total heat loss over the tube length is 381.15 W. The specific heat capacity, density, and viscosity of milk are 3.85 kJ kg$^{-1}$ K$^{-1}$, 1020 kg m$^{-3}$, and 1.20 cP, respectively. The Reynolds number for the flow is _________ (rounded off to the nearest integer). Given: Acceleration of gravity $ g = 9.81 \ \text{m/s}^2 $ and $ \pi = 3.14 $

Apple juice flows through a steel pipe having thermal conductivity of 50 W $m^{-1} \text{K}^{-1} $. The outer surface of the pipe is exposed to ambient environment. The inside diameter and thickness of the pipe are 3 cm and 1.5 cm, respectively. The overall heat transfer coefficient based on inside area is 25 W$ m^{-2} \text{K}^{-1}$. If the internal convective heat transfer coefficient is 30 W $m^{-2} \text{K}^{-1}$, the external convective heat transfer coefficient (in W $m^{-2} \text{K}^{-1} \textbf{}$ ) Will be _________ (round off to two decimal places).}
