Elizabeth Pakenham, Countess of Longford undergraduate at Lady Margaret Hall, Oxford. "Able, articulate and beautiful", in the words of "The New York Times", she was "the Zuleika Dobson of her day, with undergraduates and even dons tumbling over one another to fall in love with her". A few years after her graduation, on 3 November 1931, she married Frank Pakenham, later 7th Earl of Longford, who died in August 2001. Her obituary by the BBC said the marriage was "famously harmonious." "The New York Times", in its review of "The Pebbled Shore", called Lady Longford "easily the best writer in what is predominantly a literary
Evolution from Francis Turbine to Kaplan Turbine speed (N) is directly proportional to Flow (Q) and inversely proportional to Head (H). On the other hand, Francis turbine works on low Specific speeds i.e., high pressure heads. In the figure, it can be seen that the increase in Specific speed (or decrease in Head) have following consequences: Hence, these are the parameter changes that has to be incorporated in converting a Francis turbine to Kaplan turbine. Evolution from Francis Turbine to Kaplan Turbine Francis turbine converts energy at high pressure heads which are not easily available and hence a turbine was required to convert the energy at low
