Answer:
At the point of minimum pressure,
Solution:
As per the question;
Critical Mach no. for the air foil,
= 0.8
Now, for the value of the minimum pressure point:
Pressure of the air foil is critical, when
Now,
(1)
When M = 1:
(2)
When :
(3)
Now, from the eqns (1), (2) and (3):
Answer:
Explanation:
The temperature can be defined as the measurement of the intensity of the heat present in the object. Fahrenheit, kelvin and centigrade are the common scale used for measuring Temperature.
Given:
T1=170C
To convert to Kelvin
= 17+273 =290K
T1 = 290K
Pressure (P)= 95KPa
Specific heat ratio = CP/CV= K
WhereK=1.005/0.718
K = 1.4
The final temperature can be calculated using the formula below.
T2 = CP/CV × T1
=. K × T1
T2 = 1.4 × 290
Answer:
the order higher is 3p79g5t88=yv5379
Answer:
5.833
Explanation:
Coefficient of Perfomance (COP) is the ratio of refrigeration effect to power input.
where RE is refrigeration effect and P is power input
Here, the power input is given as 30 kW
We also know that 1 ton cooling is equivalent to 3.5 kW hence for 50 tons, RE=50*3.5=175 kW
Now the
Answer:
150 N
Explanation:
Moment is the product of force and distance:
27 N·m = F·(0.180 m)
F = 27 N·m/(0.180 m) = 150 N
The force required to produce the desired moment is 150 N.
