One ton of marine fishery products are to be brought down from $32^{\circ} \mathrm{C}$ temperature to $-18^{\circ} \mathrm{C}$ in half an hour time using a plate freezer. The freezing point of $85 \%$ water (based on total mass of the product) present in the fish is $-0.3^{\circ} \mathrm{C} .$ Specific heat capacities of fresh and frozen fish solids $(15 \%$ of total mass $)$ are 3.2 and $1.8 \mathrm{~kJ} \mathrm{~kg}^{-1} \mathrm{~K}^{-1},$ respectively. Specific heat capacity of fresh water is $4.2 \mathrm{~kJ} \mathrm{~kg}^{-1} \mathrm{~K}^{-1}$ and that of ice is $2.2 \mathrm{~kJ} \mathrm{~kg}^{-1} \mathrm{~K}^{-1}$. Latent heat of crystallization of water is $335 \mathrm{~kJ} \mathrm{~kg}^{-1}$. For freezing the products, the compressor power consumption with a vapour compression refrigeration cycle (coefficient of performance, 3.66) is____________ $\mathrm{kW}$

Mycobacterium tuberculosis is having decimal reduction time of $13.5 \mathrm{~s}$ at $72^{\circ} \mathrm{C}$. The count of the organism is to be reduced by eight logarithmic cycles in milk pasteurization with adequate holding at a temperature of $85^{\circ} \mathrm{C}$. If $\mathrm{Q}_{10}$ value for the organism is $7.5,$ the minimum holding time for the desired sterility of this particular organism at $85^{\circ} \mathrm{C}$ is_______________ seconds.

We hope we have given the updated helpful answer / content for your query in an easily accessible format to help you in preparing adequately. We do offer free support materials, 11th maths guide 11th maths guide 12th maths guide 10th maths guide, also for all the classes books and guide to all the students who sign up for SaraNextGen. Apart from traditional textbook queries, we've got conjointly provided further high order level thinking issues, that are seemingly to be expected in boards and competitive exams. It includes conceptual queries, MCQs, Long and short answer type queries, etc. These Questions are designed to learn each student and academics by providing chapter-wise further issues focusing totally on testing conceptual information with applications. Here, we've got provided a number of the necessary ways in which within which the solutions of all the Questions will profit students of class 1 to 12.
