Answer:
The surface temperature is 921.95°C .
Explanation:
Given:
a=25 cm ,P=350 hp⇒P=260750 W
Power transmitted W and remaining will lost in the form of heat.This heat transmitted to air by the convection.
h=230
Actually heat will be transmit by the convection.
In convection Q=hA
So
T=921.95°C
So the surface temperature is 921.95°C .
Answer:
percentage change in volume = 0.00285 %
Explanation:
given data
bulk modulus = 3.5 × N/m²
bulk stress = N/m²
solution
we will apply here bulk modulus formula that is
bulk modulus = ...............1
put here value and we get
3.5 × =
solve it we get
bulk strain = 2.8571 ×
and
bulk strain =
so that percentage change in volume is = 2.8571 × × 100
percentage change in volume = 0.00285 %
