Answer:
Explanation:
Hello,
In this case, for the inlet stream, from the steam table, the specific enthalpy and entropy are:
Next, for the liquid-vapor mixture at the outlet stream we need to compute its quality by taking into account that since the turbine is adiabatic, the entropy remains the same:
Thus, the liquid and liquid-vapor entropies are included to compute the quality:
Next, we compute the outlet enthalpy by considering the liquid and liquid-vapor enthalpies:
Then, by using the first law of thermodynamics, the maximum specific work is computed via:
Best regards.

Answer:
Die of intoxication by water first
Explanation:
We assume that the weight of the man is 154.35 pounds which is 70 kg
LD50 water = 90g per kg
Maximum concentration = 90x70
= 6300grams
Convert grams to liters
6300/100
= 6.3 litres
From here we get amount of kool aid
6.3 x 1.97x10^-4
= 1.24x10^-3
= 1.24grams
1.24 grams is below 420 kool aid is lower than LD50 with about 6 grams for 1 kg (6x70kg = 420). So 420 is lethal dose. But 1.24 is less than this so the man has to die of water intoxication first.
The type of type of building construction can include materials with no fire-resistance ratings in limited quantities is type 2.
Although many buildings appear to be similar at first appearance, their cost and durability—particularly in an emergency—are affected by the underlying materials. Building codes categorize all structures into Types 1 through 5, and each Type discloses important details like fire-resistance.
Some contemporary structures are now stronger and less expensive to construct. Engineered wood and synthetic plastics, which burn readily, cause quick collapses and present significant risks for firefighters.
Type 1 constructions, which are the most fire-resistant buildings, are made of shielded steel and concrete because they can sustain high temperatures without collapsing. Type 5 constructions, on the other hand, are the least fire-resistant since they are built of flammable materials, are lightweight, and they burn out quickly. Type 2 constructions, modern structures with metal roofs and tilt-slab or reinforced masonry walls.

Answer:
Explanation:
Given that;
Thermal diffusivity 
Thermal conductivity 
Heat transfer coefficient h = ( we are to assume the imposed surface temperature ) = 20 W/m².K
Initial temperature = 150 ° C = (150+273) K = 423 K
Then coolant temperature with which the casting is exposed to = 20° C = (20+273)K = 293 K
Time = 40 seconds
Length = 20mm = 0.02 m
The objective is to determine the temperature at the surface at a depth of 20 mm after 40 seconds.
Bi == 0.02
For a wall at 0.2 Bi
Therefore;
