Suspension cultures of Panax ginseng plant cells are used to produce ginseng biomass for the health tonic market. The cells are grown in batch culture in a 2500-litre stirred bioreactor operated at 25 C and 1 atm pressure. Over a period of 12 days, 5.5x10 itres of air at 25°C and 1 atm are pumped into the reactor; off-gas containing 5.1x10 litres of oxygen leaves the vessel over the same period. About 135 kg of water is lost by evaporation during the culture. Estimate the cooling requirements

Explanation:

From the given information:

It is pertinent to understand that few things need to be considered in this process. The huge metallic vessel needs warming alongside legitimate guidelines of temperature for powerful heat need of the container(organism) in the first place. Simultaneously it is additionally appropriate to chill off the substance of the vessel and justified the cooling limit. Kindly note that it is temperature is additionally related to the encompassing pressing factor and diminished temperature is a characteristic of lower pressure, which can be considered surrounding pressure (one or lower than 1 air pressure).

SO;

Specific gravity = 1

mass of water = 135 kg which is equivalent to 135 liters

To ; we have:

1 liter = 100

5 liter = 292

∴

135 L will yield 2631.616

However, converting this into MegaJoules

Recall that:

cal/ = 1 calorie or 4.19 Joules

4.19 Joules = 4.19 × 10⁻⁶ MegaJoules

Hence;

2631.616 = (2631.616 ×  4.19 × 10⁻⁶) Mega Joules

= 0.0110264878

= 11026.47 × 10⁻⁶ Mega Joules per day
