Answer:
408 J/kg
662696.7 J/kg
Explanation:
Workdone by compression process in a pump can be isothermally expressed as :
For water at inlet pressure 1. 0 bar;
the specific values for :
saturated vapor
saturated liquid
∴ we have
= 1.0 bar = 1. 0 × 10⁵ N/m²
= 50 bar = 50 × 10⁵ N/m²
For saturated water output from condenser work; we have
W =
W =
W = 408 J/kg
For saturated vapor output from condenser
Work required :
W =
W = 662696.7 J/kg
Answer:
i) 25.04 W/m^2 .k
ii) 23.82 minutes = 1429.2 secs
Explanation:
Given data:
Diameter of steel ball = 15 cm
uniform temperature = 350°C
p = 8055 kg/m^3
Cp = 480 J/kg.k
surface temp of ball drops to 250°C
average surface temperature = ( 350 + 250 ) / 2 = 300°C
<u>i) Determine the average convection heat transfer coefficient during the cooling process</u>
<em>Note : Obtain the properties of air at 1 atm at average film temp of 30°C from the table " properties of air " contained in your textbook</em>
average convection heat transfer coefficient = 25.04 W/m^2 .k
<u>ii) Determine how long this process has taken </u>
Time taken by the process = 23.82 minutes = 1429.2 seconds
Δt = Qtotal / Qavg = 683232 / 477.92 = 1429.59 secs
