Answer:
drawing tablets
Explanation:
made it easier for artists to draw or sketch using a tablet instead of a paper
We can find the change in the enthalpy through the tables A5 for Saturated water, pressure table.
For 1bar=1000kPa:




Replacing,



With the specific volume we know can calculate the mass flow, that is


Then the heat required in input is,



With the same value required of 15000m^3/h, we can calculate the velocity of the water, that is given by,



Finally we can apply the steady flow energy equation, that is

Re-arrange for Q,




We can note that consider the Kinetic Energy will decrease the heat input.
Answer:
V=1601gal
Explanation:
Hello! This problem is solved as follows,
First we must raise the equation that defines the pressure at the bottom of the tank with the purpose of finding the height that olive oil reaches.
This is given as the sum due to the atmospheric pressure (1atm = 101.325kPa), and the pressure due to the weight of the olive oil, taking into account the above, the following equation is inferred.
P=Poil+Patm
P=total pressure or absolute pressure=26psi=179213.28Pa
Patm= the atmospheric pressure =101325Pa
Poil=pressure due to the weight of olive oil=0.86αgh
α=density of water=1000kg/m^3
g=gravity=9.81m/s^2
h= height that olive oil reaches
solving
P=Poil+Patm
P=Patm+0.86αgh

Now we can use the equation that defines the volume of a cylinder.
V=
D=3ft=0.9144m
h=9.23m
solving

finally we use conversion factors to find the volume in gallons

Answer:
Q = 125.538 W
Explanation:
Given data:
D = 30 cm
Temperature
degree celcius

Heat coefficient = 12 W/m^2 K
Efficiency 80% = 0.8


Q = 125.538 W
