Intuitively, he knew one other member of the group had died. “Who? ” “Warrant Officer Kotkov and Senior Lieutenant Annekov,” acknowledged Kalinin quietly. Petrov’s face mirrored the soreness he felt. The general practitioner had warned him prior that it was once most likely that they'd lose extra, yet that wasn’t a lot support now that fact had reared its grotesque head. Shaken via the scoop, he leaned seriously at the chair to regular himself. Kalinin sympathized together with his commander; he had felt an analogous soreness a number of hours previous. with no being triggered, he supplied extra info. “Kotkov died from critical blood loss, whereas Annekov died from issues of smoke inhalation. I’ve had the our bodies put in a single of the portside torpedo tubes. ” together with his jaw firmly clenched, Petrov nodded his realizing and approval. combating to carry himself jointly, he was once slightly in a position to ask his subsequent query. “What is our prestige? ” “Oxygen is at seventeen and a part percentage and carbon dioxide is at one percentage. We introduced six air-regeneration devices on-line at 2100 hours final evening. the second one set of regeneration cassettes should be depleted inside a few hours. The devices are fairly well-liked by the workforce straight away. ” each one air-regeneration cassette contained a chain of chemical plates lined with hugely reactive potassium hyperoxide and sodium superoxide compounds. those chemical substances reacted with the moisture within the air to soak up carbon dioxide and substitute it with oxygen. A useful aspect impact of the chemical response was once that it generated loads of warmth, which was once exhausted into the compartment through a blower in each one regeneration unit. It was once radically hotter close to the sort of machines and the team tended to congregate round them. “We have performed a list of our emergency nutrients and water supplies,” persevered Kalinin, “and with right rationing, we will cause them to final for 6 or seven days. leader Engineer Lyachin, even though, believes he can achieve entry to 1 of the potable water tanks, which might tremendously expand our water reserves. ” At this aspect, Kalinin stopped, shook his head, and commenced to chuckle. This abrupt swap stuck Petrov off defend, and it snapped him out of his darkish temper. staring at Kalinin chortle, Petrov questioned no matter if his starpom was once already struggling with oxygen deprivation. “What’s so humorous, Vasiliy? ” “Ohhh, it’s Sergey and his boys,” chortled Kalinin. “For the final six hours they've been calculating and debating at the most sensible option to allocate strength from the reserve battery. Our leader Engineer referred to as it a realistic workout. ” The starpom truly came across the engineers’ wording to be particularly funny, and he needed to pause earlier than he was once in a position to communicate in actual fact. “Anyway, after a lot dialogue and brandishing of calculators, the engineering division has get a hold of a plan to in short flip off regeneration devices every day and use the ability to warmth up a few water to make tea and low for the workforce. do you know that these sneaky engineers had their very own stash of espresso and tea? ” Petrov shrugged. “I wouldn’t be shocked.
