A proposed steam power plant design consists of an ideal Rankine cycle with reheat and regeneration. Steam enters Turbine 1 at P1 and T1 at the rate of m1 and exits at P2. A fraction (y') of the steam exiting Turbine 1 is diverted to an open feedwater heater while the remainder is reheated to T3 before entering Turbine 2. The condenser operates at P4. Saturated liquid exits the condenser and is fed to Pump 1. The outlet of Pump 1 is fed into the open feedwater heater. Saturated liquid exits the feedwater heater and is fed to Pump 2. All turbines and pumps are isentropic.
--Given Values--
m1 (kg/s) = 50
P1 (Bar) = 140
T1 (C) = 560
P2 (Bar) = 10
T3 (C) = 500
P4 (Bar) = 0.08

write a VBA code to convert an arbitrary positive binary fractional number (0< number<1) to equivalent decimal number. the code should acquire the binary fraction number in the format"0.xxxxxx"from input box, then return the equivalent decimal number in a message box. in the code, you may need to use VBA function "mid(_,_,_)" to pick up a specific symbols or characters from a string. you can use below conversion as benchmark to verify and debug your code:
(0.1011)2 = (0.6875)10

Two cylinders of oxygen are connected to each other by a valve. The first tank is 50 liters in volume and contains oxygen at 27 °C and a pressure of 140.37 kPa, and the corresponding values for the other tank are 30 liters, 89 °C and 62.73 kPa. If the valve connecting the tanks is opened and the tanks are allowed to reach some equilibrium condition with the temperature being 50 °C. Answer the following: (a) the equilibrium pressure, (b) the heat transfer between both tanks and the surroundings and the direction of the heat transfer, and (c) the internal energy in the final state if the tanks were insulated.

Conventional thinking in product development has been that
innovation starts in advanced
developed countries like the United States and Japan. Products
marketed in
countries where the average income is much lower often are older
models of U.S. products
or used but still serviceable equipment. Several U.S. multinational
companies have
established R&D labs in India and China. Originally this was to
take advantage of the
large number of well-educated engineers who could be employed at
salaries much lower
than the going U.S. rate, but soon it was found that these
engineers were adept at developing
products for sale to the mass markets in these local countries.
Typically these are
products with somewhat reduced functionality, but they still are
useful quality products.
Now these U.S. companies are beginning to market these products in
the United States
as a low-cost product line that is attractive to a new low-end
market segment.
Search the business literature for examples of this new approach to
trickle-up product
innovation. Discuss advantages of this new approach to product
development and discuss
possible risks.

. A steam main (outside diameter of 16.8 cm and inside diameter of 15.4 cm) is covered with 5-cm of high temperature insulation (k = 0.095 W/m. K) and 3.8 cm of lower temperature insulation (k = 0.07W/m. K). Calculate the heat loss from 150 m pipe assuming that inner and outer surface temperatures of the insulation are 450 and 30 °C, respectively. Also determine the temperature at the interface between two layers of insulation (10 points).
