Bending effect!! Whenever the orientation of the diffracting planes changes when the diffracting planes bend, the contrast changes.
Answer:
hello your question lacks the required diagram attached below is he missing diagram and solution
answer : 17480.618 Ib
Explanation:
To calculate the weight of block neccessary to prevent the gate from opening , we will first calculate the force of water from the hinge
next we will calculate moments about the force of water and the force about the hinge of the gate
attached below is the complete solution and free hand sketch
from the sketch : h1 = 7 ft, x = 2ft, h2 = 5ft,
Answer:
hello the figure attached to your question is missing attached below is the missing diagram
answer :
i) 1.347 kW
ii) 1.6192 kW
Explanation:
Attached below is the detailed solution to the problem above
First step : Calculate for Enthalpy
h1 - hf = -3909.9 kJ/kg ( For saturated liquid nitrogen at 600 kPa )
h2- hg = -222.5 kJ/kg ( For saturated vapor nitrogen at 600 kPa )
second step : Calculate the rate of heat transfer in boiler
Q1-2 = m( h2 - h1 ) = 0.008( -222.5 -(-390.9) = 1.347 kW
step 3 : find the enthalpy of superheated Nitrogen at 600 Kpa and 280 K
from the super heated Nitrogen table
h3 = -20.1 kJ/kg
step 4 : calculate the rate of heat transfer in the super heater
Q2-3 = m ( h3 - h2 )
= 0.008 ( -20.1 -(-222.5 ) = 1.6192 kW
