Let’s consider a propeller aircraft propeller diameter of 24 feet then, what would be the minimum value of clearance that is required for safe operation of propeller typically?
Determine thrust of propeller if propeller efficiency is 85%. Propeller is assumed to be operated with 1200 bhp and 350ft/s of velocity.
Consider the following statements: 1. The distinguishing features of a radial flow reaction turbine are – (i) only a part of the total head of water is converted into velocity head before it reaches the runner and (ii) the flow through water completely fills all the passages in the runner. 2. Kaplan turbine is essentially a propeller working in reverse, and its blades are so mounted that all the blade angles can be adjusted simultaneously by means of suitable gearing even as the machine is in operation 3. A draft tube is pipe of gradually increasing cross-sectional area which must be airtight, and under all conditions of operation, its lower end must be submerged below the level of the discharged water in the tailrace. Which of the above statements are correct? 
In a turbine, where are the draft tubes mounted?

The important design and operating considerations for Extended-Surface Compact Heat Exchangers are: (1) Both fluids may have high or low heat transfer coefficients (2) As the tubes are very narrow (low DH), the fluid used should not be corrosive as effective cleaning of tubes is not possible. (3) The fluid pressure drop calculation is important as a regulatory method to ensure long life of the tubes. (4) Unlike shell and tube type heat exchangers, these are limited when it comes to operating pressure and temperature.
