Дано:

ρ=1000кг/м³

g=10H/кг

h=11.9м

Найти:

p-?

Давление на стенки трубы зависит от высоты, с глубиной оно увеличивается.

p=ρgh=1000кг/м³•10Н/кг•11.9=119кПа

ПО ЭТОМУ ТЕКСТУ:

The management of the company is called the Board of Directors (not Managers) headed by the Chairman ( = the President Am.) There is usually a Managing Director and in the case of big companies there may be several Joint Managing Directors.

A Manager in British companies is the person who is head of a department – Sales, Export, Works (Production), Staff, ect.

So there are Sales Managers, Export Managers, Works (Production) Managers, Staff Managers, ect.

A general Manager has managers, working under his control, and receives his instruction from the Managing Director.

By British Company Law (the Companies Acts of 1948 and 1985) a limited company (public or private) must have a Company Secretary whose duties are manifold. First he is the clerk to the Directors: he is to keep Registers of Directors and Members; arrange for proceeding at Director’s and shareholder’s meeting, prepare notices for the calling of these meeting, attend them and advise directors at board meeting on the legal, accounting and tax implications of any proposed business move as well as keep minutes and write reports (the minutes of a meeting are usually concise records pf resolutions or decisions reached, and the reports are more extensive and give details of discussions, arguments for or against the resolutions, and so on). Second he represents his company and in this capacity he supervises the working of the staff and the maintenance of staff records (if there is no special staff manager), finally he is often responsible for the accounting and handling of contracts. Thus he is link between the company and the public.

The Company Secretary must me a properly qualified person, and be able to fulfill his routine duties well. He is supposed to have training in company law, accountancy and many other subjects. He is expected to be a part-lawyer, part-economist, part-administrator and part-accountant.

But it takes a good deal more than professional qualifications to male a good company secretary: «he must be businessman and humanitarian, lawyer and visionary» (as one of the English newspapers puts it).
