Water enters a tube of D=5-cm in diameter at Tm,=21°C with a flowrate of rm=0.18- kg/min. The tube is wrapped with a resistance heater pad providing a constant heat flux of q!=2.4-kW/m?. Assuming that the flow is both hydrodynamically and thermally full developed, determine the length of the tube (in meters) required to heat the water to Tm,o=123°C.

I need the answer as soon as possible
An isosceles triangle channel having an apex angle of 60 ° and length of 20 m is being heated uniformly with electric heaters. Water flows through this channel with an inlet temperature of 15 °C and mass flow rate of 1 kg/s and is 10 m being heated to 45 °C at the exit of the tube. Assuming the water flow is fully developed through the channel what is the average convection heat transfer coefficient? Also determine the pumping power. 10 m 16 m
Water at 10 C flows in a 1.25-cm-diameter pipe at a rate of 1.33 L/min. The hydrodynamic entry length (in meters) is

Hello! I'd like help with the following exercise, from Levenspiel's "Engineering Flow and Heat Exchange". Leftover air at 20ºC and 100kPa is driven by a fan through a horizontal galvanized conduit of 1 m in diameter and 10m in length at a speed of 10 m/s. What size motor should be used if its efficiency is 90% and that of the fan is 20%? I'm not sure where to start. My professor hasn't explained much about this subject.

I need a solution ASAP Problem -1 A tank is initially empty. A liquid with p = 62.4 Ibm/ft is poured into the tank at a constant mass flow rate of m = 7 Ibm/s. The tank has cross-sectional area A = 0.2 ft, and the fluid in the tank has a variable height H(t). There is a hole at the bottom of the tank. The fluid flows out of the tank at a rate proportional to the fluid height: me = kH, where k = 1.4 Ibm/ft/s. Find H(t). A sketch is given in Fig. P.1. Figure.P.1: Sketch of tank filling problem
